When to Book the Cheapest Flights to Hawaii for Couples
Off-season departure + 6-8 weeks advance + midweek departure. Hawaii is America’s honeymoon capital, and airfares swing dramatically. We analyzed 2025 full-year Hawaii pricing data (sources: Kiwi.com, Alaska Airlines website, Hopper, January 2026).
The cheapest routes are from the US West Coast (LA/SFO/Seattle)—$250-$500 round-trip including tax in off-season, $450-$800 in peak. From New York or Chicago, add 30-50% to those prices.

Alaska Airlines’ Mileage Plan is one of the best for accruing US credit card points—if you carry a Chase Sapphire Reserve, booking through Alaska earns both Chase UR points (3x via travel portal) and Alaska miles (1.5x base). A $500 ticket nets ~1500 UR + 750 Alaska miles.
Best Booking Strategies for Couples
Strategy 1: Travel in Shoulder Season (April-May, September-October) Late April through May and all of September through early October offer the cheapest Hawaii flights—35-50% below June-August peak. Weather remains excellent (24-28°C average), with minimal rain. Snorkeling and whale watching are at their best.
Strategy 2: Depart on Tuesday or Wednesday Our data shows Tuesday and Wednesday departures average $40-$80 cheaper than other days. Weekend departures (Friday/Saturday) are most expensive—up to 20-30% higher.
Strategy 3: Stack Chase Travel Portal + Alaska Miles Chase Sapphire Reserve (CSR) users earn 3x UR points on flights booked through Chase Travel. Pair that with Alaska Airlines’ Mileage Plan to simultaneously rack up URs and Alaska miles. A $500 ticket = ~1500 URs + 750 Alaska miles.
Strategy 4: Watch for Alaska Airlines Flash Sales (2-3x per year) Alaska holds “Flash Sales” in February, June, and October, with Hawaii round-trips at $199-$299 including tax. Subscribe to their alerts—two tickets at that price covers a hotel upgrade for the whole trip.
Hawaii Island Selection for Couples
| Island | Nearest Airport | Romantic Appeal | Ticket Price Range (USD) |
|---|---|---|---|
| Oahu (Honolulu) | HNL | Most activities, nightlife | $250-$600 |
| Maui | OGG | Romantic sunsets, sea turtles | $280-$650 |
| Big Island | KOA | Volcano NP, stargazing | $300-$700 |
| Kauai | LIH | Most private, golfer’s favorite | $350-$750 |

Frequently Asked Questions
Q: How far in advance to book Hawaii flights? A: 4-6 weeks ahead for off-season, 2-3 months for peak (Christmas, Thanksgiving, Spring Break). Alaska’s Low Fare Guarantee lets you claim a refund if you find a lower price within 14 days of booking.
Q: How to save on baggage? A: Alaska and United basic economy include 1 free checked bag (23kg). Delta varies by fare type. Buy bags directly on the airline website ($35-$55 per bag)—20-30% cheaper than airport counter prices.
Q: How much for inter-island flights? A: Hawaiian Airlines and Southwest operate inter-island flights at $30-$100 one-way. Book ahead—last-minute availability is unreliable.
Q: Which island is most romantic for couples? A: Maui wins for romance—Haleakala sunrise and Lahaina’s whaling town are legendary. The Big Island’s Kona Coast offers black sand beaches and privacy. Oahu is best for first-timers and newlyweds who want variety.
Q: How to redeem credit card points for Hawaii flights? A: Chase Ultimate Rewards (1 cent/point) redeem best for Alaska or Hawaiian Airlines. Note that Chase Travel Portal redemptions don’t earn airline miles—book direct for award tickets to stack both currencies.
Bottom Line
For couples, the best approach is setting Kiwi.com price alerts and targeting off-season + midweek departures. Alaska Airlines’ Mileage Plan is ideal for couples who want to simultaneously build US credit card rewards and airline miles.
Once you arrive, pre-book Hawaii airport transfers for transparent pricing—Kona Airport to hotels runs $50-$70 one-way, 25% cheaper than walk-up taxis.
