If you have ever boarded a Spring Airlines (春秋航空) flight to Japan and discovered at check-in that your suitcase was 3 kilograms over the limit, you already know the airline plays hardball with baggage. No leniency, no goodwill waivers, no rounding down — just a clean, non-negotiable excess fee charged on the spot in cash or card. The airline that built its reputation on rock-bottom fares has an equally notorious reputation for baggage upsells, and understanding exactly how the system works is the difference between a $15 suitcase top-up and a $75 gate-side shock.
This guide is built for the 2026 traveler flying Spring Airlines Japan routes — covering every fare class, every weight tier, every fee channel (online, counter, and gate), and every strategy to pack smarter, pay less, and walk onto your flight without a second thought about what your bag weighs.

Understanding Spring Airlines Fare Classes and Their Baggage Implications
Spring Airlines operates three distinct fare tiers on its Japan international routes, and the baggage allowance is fundamentally different for each one. This is the single most important thing to understand before booking.
| Fare Type | Carry-On Allowance | Free Checked Baggage | Best For |
|---|---|---|---|
| Lucky Spring (Saver) | 7 kg (15.4 lb) | 0 kg — no free checked bag | Ultra-budget travelers carrying only a personal item |
| Spring (Standard) | 7 kg (15.4 lb) | 20 kg (44 lb) | Most travelers who pack a standard suitcase |
| Spring Plus (Premium) | 10 kg (22 lb) | 30 kg (66 lb) | Shoppers, families, or anyone who overpacks |
The Lucky Spring fare is aggressively cheap — sometimes 30–50% below the Spring fare on the same route — but it deliberately includes zero checked baggage. Travelers who choose this tier are expected to travel with only a cabin bag. If you need to check a bag on a Lucky Spring ticket, you will pay the full excess baggage fee from scratch.
The Spring and Spring Plus tiers include their respective free checked allowances automatically, but critically, those allowances can only be expanded once in advance via the Spring Airlines website or call center. Any additional weight beyond what you pre-purchased must be settled at the airport counter at a significantly higher rate.
A nuance many travelers miss: the carry-on weight limit (7 kg for Lucky Spring and Spring; 10 kg for Spring Plus) is enforced at the boarding gate, not just at check-in. If your cabin bag is weighed and found to exceed the limit, it will be pulled from you, reclassified as checked baggage, and you will pay the excess fee on the spot. There is no appeal, no negotiation, and no “I’ll wear my heavy jacket” workaround accepted at the gate.
The Real Cost of Checked Baggage: 2026 Fee Schedule
This is where Spring Airlines separates the prepared from the panicked. The fee you pay depends on three variables: how much extra weight you need, where you buy it (online before departure, at the airport counter, or at the boarding gate), and which currency you pay in.
Pre-Purchase Fees (Online / Call Center) — Japan International Routes
Purchasing additional checked baggage weight before your departure date via the Spring Airlines website or call center is the cheapest option. Rates below are tax-inclusive and apply per passenger per segment.
| Weight Tier | JPY (Online/Call Center) | CNY (Online/Call Center) | Approx. USD |
|---|---|---|---|
| Up to 5 kg | ¥2,500 | ¥150 | ~$17 |
| Up to 10 kg | ¥4,500 | ¥270 | ~$30 |
| Up to 15 kg | ¥6,500 | ¥390 | ~$44 |
| Up to 20 kg | ¥8,000 | ¥480 | ~$54 |
| Up to 25 kg | ¥9,000 | ¥540 | ~$60 |
| Up to 30 kg | ¥10,000 | ¥600 | ~$67 |

Airport Counter Fees — Japan International Routes
If you miss the advance purchase window, you can still buy extra baggage weight at the airport check-in counter on the day of departure. The fees are approximately double the online rate.
| Weight Tier | JPY (Airport Counter) | CNY (Airport Counter) | Approx. USD |
|---|---|---|---|
| Up to 5 kg | ¥5,000 | ¥300 | ~$34 |
| Up to 10 kg | ¥9,000 | ¥540 | ~$60 |
| Up to 15 kg | ¥13,000 | ¥780 | ~$87 |
| Up to 20 kg | ¥16,000 | ¥960 | ~$107 |
| Up to 25 kg | ¥18,000 | ¥1,080 | ~$121 |
| Up to 30 kg | ¥20,000 | ¥1,200 | ~$134 |
Boarding Gate Fees — Japan International Routes
This is the most expensive option. Gate baggage fees are reserved for passengers who arrive at the boarding gate with non-compliant cabin bags. Spring Airlines gate staff will intercept bags that exceed carry-on dimensions or weight and charge a premium to gate-check them.
| Scenario | JPY | CNY | Approx. USD |
|---|---|---|---|
| Gate bag ≤ 10 kg | ¥6,000 | ¥360 | ~$40 |
| Gate bag > 10 kg | ¥10,000 | ¥600 | ~$67 |
| Nonconforming bag ≤ 20 kg (International) | ¥10,000 | ¥600 | ~$67 |
| Nonconforming bag > 20 kg (International) | ¥17,000 | ¥1,020 | ~$114 |
Bottom line: Pre-purchasing 20 kg of extra checked baggage online costs approximately $54 USD. The same 20 kg at the airport counter costs approximately $107 USD — nearly double. At the gate, it is even worse. The math is unambiguous: buy your extra baggage online before you leave for the airport.
Weight and Size Restrictions: What You Need to Know Before You Pack
Spring Airlines enforces two separate constraints on checked baggage: weight per bag and total linear dimensions per bag. Both matter, and both have hard limits.
Weight Limits
Each checked bag must weigh 30 kg (66 lb) or less. This is a firm regulatory limit — bags exceeding 30 kg cannot be loaded onto the aircraft for safety and handling reasons. If you need to transport more than 30 kg in a single bag, you must split it into two separate bags, each paying its own fee.
For passengers with extremely heavy items, Spring Airlines charges an overweight surcharge of ¥1,500 (approximately $10 USD) per kilogram for any weight above 30 kg, but this is only available at the airport counter — advance online purchase for weights above 30 kg is not accepted.
Size Restrictions
The size rule is simple but consequential: the sum of all three dimensions (length + width + height) of any checked bag must not exceed 203 cm (80 inches). A standard large suitcase measuring 76 × 51 × 31 cm totals 158 cm — well within the limit. A bulky expedition bag or an irregularly shaped case can easily breach this threshold without feeling particularly oversized.
If your bag’s three-side sum exceeds 203 cm but stays within 277 cm on the longest single side, it qualifies as oversized baggage and incurs an additional fixed surcharge. If the longest side alone exceeds 277 cm, the bag cannot be transported.
| Restriction | Limit | Notes |
|---|---|---|
| Max weight per bag | 30 kg (66 lb) | Above 30 kg: ¥1,500/kg at counter only |
| Max linear dimensions | 203 cm (80 in) sum of L+W+H | Oversized: 203–320 cm sum, longest side ≤ 277 cm |
| Longest single side | ≤ 277 cm | Above this: bag cannot be transported |
| Carry-on weight (Lucky Spring / Spring) | 7 kg (15.4 lb) | Enforced at check-in AND boarding gate |
| Carry-on weight (Spring Plus) | 10 kg (22 lb) | Larger carry-on dimensions: 55 × 40 × 20 cm |
Smart Strategies to Reduce Your Baggage Bill
The difference between a well-prepared Spring Airlines traveler and a startled one often comes down to four or five concrete decisions made before the trip. Here is what actually works.
Buy Extra Baggage Weight Before Departure
This cannot be said enough. The advance purchase window closes two hours before your scheduled departure time. Within that window, you can log in to your Spring Airlines reservation, navigate to “Manage My Reservations,” click “All the Extras,” and add up to 30 kg of extra checked baggage in 5 kg increments.
One critical constraint: advance baggage purchases are limited to one transaction per passenger per leg. You cannot buy 10 kg, discover it is not enough, and then buy another 5 kg. If you underestimated, the remainder must be settled at the airport counter at the higher counter rate. This makes honest self-assessment of your packing needs essential — there is no second chance at the online rate.
Know the 5 kg Increment Rule
Spring Airlines charges by weight brackets, not by the kilogram. If you need 7 kg of extra allowance, you will be charged for the 10 kg bracket at the online rate (¥4,500 / ~$30 USD). Rounding up is unavoidable, so calibrate your purchase to land as close as possible to an actual bracket boundary.
Split Bags Strategically
If your trip involves two travelers on the same booking, the free checked baggage allowances can be combined — but only if both passengers’ bags are checked in at the same time by the passenger whose name is on the booking. This allows a family of two traveling on Spring fares to pool 40 kg of free allowance before paying a single yen of excess fees.
Additionally, if you are on a return journey from Japan carrying purchased goods, consider splitting heavy items across two bags. Each bag is charged independently, which can prevent a single bag from tipping into the next pricing bracket.
Use a Luggage Scale Before You Leave
A digital luggage scale costs between $10 and $25 USD and pays for itself on the first Spring Airlines flight. Weigh your fully packed bag at home before heading to the airport. Include the weight of any duty-free purchases you plan to bring aboard. This eliminates the risk of an on-the-spot overweight discovery at check-in or the gate.
Consider Shipping Heavy Items Instead
For travelers returning from Japan with heavy purchases — electronics, sake, traditional crafts, or other dense goods — the cost of international parcel shipping (Japan Post EMS, Yamato Transport, or DHL) can be competitive with or cheaper than Spring Airlines excess baggage fees on a per-kilogram basis. EMS shipping from Japan to the United States starts at approximately ¥2,800 for 2 kg (~$19 USD), making it competitive with ¥2,500 for 5 kg of Spring Airlines extra allowance. For items over 15 kg total, shipping becomes unambiguously cheaper.

Packing Tips to Maximize Every Kilogram
With no free checked baggage on the Lucky Spring fare and a relatively tight 20–30 kg free allowance on other tiers, Spring Airlines rewards deliberate, efficient packing. Here is how to approach it.
Wear your heaviest items. Shoes, jackets, and sweaters are the densest items in any suitcase. Wear your bulkiest footwear and layer a heavy outer shell through security and onto the plane. You can change once aboard or at your destination.
Downsize your toiletries. The 100 ml liquid rule applies to carry-on bags only. For checked bags, there is no restriction — but full-size toiletries are dead weight. Transfer everything to travel-sized containers or purchase toiletries at your destination. Japan has exceptional convenience stores (7-Eleven, Lawson, FamilyMart) on every corner.
Vacuum compression bags are your single best investment. A set of four compression bags costs under $15 USD and can reduce the volume of clothing by 50–60%. This matters because Spring Airlines enforces a weight limit, not a volume limit on checked bags — so compressing clothes to reduce weight from fabric fibers being loosely packed is a direct money-saver.
Weigh carry-on before leaving for the airport. The 7 kg carry-on limit catches many experienced travelers off guard. A full laptop (2–3 kg), camera gear (1–2 kg), and a jacket (1–2 kg) can push a seemingly reasonable cabin bag past the threshold before you even add clothing.
Alternatives: Budget Airlines Competing on the Same Routes
Spring Airlines Japan routes face direct competition from several other low-cost carriers serving the Japan market. Here is how Spring Airlines compares on baggage policy.
| Airline | Free Carry-On | Free Checked (Base Fare) | Lowest Extra Weight Rate (Online) | Oversized Surcharge |
|---|---|---|---|---|
| Spring Airlines / Spring Japan | 7 kg (Lucky Spring/Spring) / 10 kg (Spring Plus) | 0 kg / 20 kg / 30 kg by fare tier | ¥2,500 / 5 kg (~$17 USD) | ¥8,000 (~$54 USD) |
| Peach Aviation | 7 kg (base) | 0 kg on Peach Basic; 20 kg on Peach Plus | ¥1,000 / 3 kg (~$7 USD/3 kg) | ¥3,000 (~$20 USD) |
| Jetstar Japan | 7 kg (base) | 0 kg on Starter; 20 kg on Starter Plus | ¥800 / 3 kg (~$5 USD/3 kg) | ¥3,000 (~$20 USD) |
| AirAsia X (Japan routes) | 7 kg | 0 kg on Low Fare; 20 kg on Low Fare+ | ¥900 / 5 kg (~$6 USD) | ¥3,000 (~$20 USD) |
Note: Peach Aviation, Jetstar, and AirAsia X rates are approximate and sourced from each airline’s official baggage pages as of Q1 2026.
Spring Airlines is not the cheapest option per kilogram for extra baggage — Peach and Jetstar both offer lower per-kilogram rates on add-on purchases. However, Spring Airlines’ Spring Plus fare at 30 kg free checked baggage often undercuts competitors on total trip cost when you factor in what competitors charge for equivalent total baggage (base fare plus 20–30 kg of add-ons). The real comparison requires running the numbers for your specific travel dates and route.

Special Items, Sports Equipment, and Oversized Baggage
Traveling with golf clubs, surfboards, diving gear, skis, or a bicycle adds a separate fee layer that operates independently of the weight-based excess baggage charges.
| Item | Online Pre-Purchase | Airport Counter | Approx. USD (Counter) |
|---|---|---|---|
| Oversized bag (sum of sides > 203 cm) | Not available | ¥8,000 | ~$54 |
| Golf equipment (1 set) | Not available | ¥4,000 | ~$27 |
| Diving gear (1 set) | Not available | ¥4,000 | ~$27 |
| Skis (1 pair) | Not available | ¥4,000 | ~$27 |
| Snowboard (1) | Not available | ¥4,000 | ~$27 |
| Surfboard (1) | Not available | ¥8,000 | ~$54 |
| Bicycle (1) | Not available | ¥8,000 | ~$54 |
These fees apply per item per passenger and must be paid at the airport check-in counter — there is no advance online purchase option for sports equipment. Note that surfboards and bicycles share the same oversized baggage category and fee, both capped at ¥8,000.
Free allowances for special items: Infants traveling with a baby stroller, infant car seat, or carry-cot get one such item checked for free per infant. Passengers traveling with a personal wheelchair or mobility device also get one item checked at no charge, though size restrictions may apply.
Frequently Asked Questions
Can I change my checked baggage allowance after I have already pre-purchased it? No. Spring Airlines allows only one advance baggage purchase per passenger per flight leg. If you need more weight after purchasing, you must pay the additional cost at the airport counter at the higher rate. There is no online modification or cancellation of pre-purchased baggage allowances — the fee is non-refundable even if your bag ends up being lighter than purchased.
What happens if my checked bag weighs exactly 31 kg? Bags over 30 kg are charged an excess fee of ¥1,500 (approximately $10 USD) per kilogram for each kilogram above 30. A 31 kg bag would incur a ¥1,500 surcharge. Bags exceeding 30 kg cannot be pre-purchased online — you must settle this at the airport counter. If your bag is closer to 35+ kg, it is almost always cheaper to split the contents into two bags, each under 30 kg, each within your fare’s free allowance or a separate pre-purchased weight bracket.
Are duty-free purchases from the airport included in my carry-on allowance? Yes, with a nuance. Items purchased at the duty-free shop after security are treated as carry-on baggage and counted within your 7 kg carry-on limit. However, Spring Airlines gate staff have been known to weigh duty-free bags alongside regular carry-on. Keep your duty-free receipts visible in case of dispute, and factor the weight of duty-free bags into your carry-on calculation before arriving at the gate.
Is the free checked baggage allowance on Spring Airlines Japan routes per person or per ticket? Per person. Each passenger has their own free allowance based on their fare class. However, passengers on the same booking can pool their free allowances. For example, two passengers traveling on Spring fares (20 kg each) can combine their free allowances to cover one 40 kg bag, as long as both bags are checked in simultaneously at the same counter by the booking holder.
Can I use Spring Airlines’ baggage service to ship items separately rather than checking them? Spring Airlines does not offer an integrated shipping service, but you can arrange for luggage collection and international shipping through third-party concierge services available at major Japanese airports. Platforms like Klook and Klook list airport luggage service options including excess baggage shipping, dedicated courier services, and luggage storage. These can be more cost-effective than Spring Airlines excess fees for very heavy or oversized items.
What is the deadline for pre-purchasing extra checked baggage online? The advance purchase window closes two hours before your scheduled departure time for international flights. For domestic flights within China, it is also two hours. This means you cannot pre-purchase baggage from the airport itself — you must do it from home, from your hotel, or anywhere with an internet connection before you leave for the airport. Once the two-hour mark passes, you are limited to the airport counter rates (approximately double online) or gate rates (even higher).
Spring Airlines is not trying to confuse you — the baggage policy is clearly documented on their website. The problem is that most travelers do not read it until they are standing at the check-in counter watching a staff member place their suitcase on a scale. A few minutes of preparation before you book and again before you pack is all it takes to avoid the most common and costly surprises.
For your accommodation in Japan, check current rates on Agoda, Booking.com, or Hotels.com to keep your total trip budget manageable alongside those baggage fees.
