- JetBlue and United have begun listing eligible flights from one another on their own sites and apps, following the launch of their Blue Sky partnership.
- Depending on the booking site, customers have the option to pay either with cash or by redeeming loyalty points and miles.
- Later phases will roll out additional features—reciprocal perks, plus JFK slot access connected to Terminal 6, are both on the list.
JetBlue Airways and United Airlines kicked off a new phase in their Blue Sky tie-up on Tuesday, opening up cross-booking for eligible flights—customers can now purchase trips operated by either airline straight from JetBlue.com, United.com, or the two companies’ mobile apps. According to both, payment options include cash as well as loyalty points and miles, shifting the partnership beyond simply shared perks and into everyday ticketing.
This rollout is significant: it lets both airlines boost their offerings without merging or tying their networks together completely. JetBlue, for one, now has a better shot at tapping into United’s broader domestic and international routes. United, on the other hand, picks up extra access to JetBlue’s markets focused on leisure travelers.
Blue Sky surfaced back in May 2025, rolled out by the airlines as a joint consumer venture, with both parties noting that U.S. regulators would need to sign off. JetBlue was seeking fresh alliances after a judge shut down its Northeast Alliance with American Airlines in 2023, Reuters wrote.
At this point, cross-selling applies to “eligible itineraries” handled by just one airline per trip. Both airlines noted that travelers browsing either website or app will find a broader mix of flight options drawn from both networks. TrueBlue points are redeemable through JetBlue’s platforms, while MileagePlus miles can be used via United’s channels, provided the flights qualify.
United’s Chief Commercial Officer Andrew Nocella said the cash-booking rollout lets travelers “plan and purchase travel across two leading networks” more easily. On JetBlue’s side, President Marty St. George labeled it an “important step” that broadens opportunities for customers to earn and redeem points.
United flights have landed on JetBlue Vacations’ Flight + Hotel bundles, the airlines said, with cruise packages set to follow. The move opens up an extra distribution route for United and hands JetBlue more packaged leisure options to pitch to travelers.
The companies said more perks are on the way this spring, with plans for priority boarding and access to preferred and extra-legroom seats. United’s MileagePlus Travel is also set to make the jump to JetBlue’s Paisly platform sometime in 2026, which will bring in options for hotels, rental cars, cruises, packages, and travel insurance.
United and JetBlue reiterated their joint strategy for expanding United’s presence at New York’s JFK. JetBlue will hand United access to as many as seven daily round-trip slots at JFK’s upcoming Terminal 6, possibly starting in 2027. Those slots—essentially takeoff and landing rights at capacity-capped airports—dictate the number of flights an airline can run.
Still, the expanded booking has its caveats. United.com won’t cover every JetBlue route, and travelers can’t always earn or use MileagePlus miles on all flights. Award seats? Airlines warn those are “capacity-controlled,” so snagging one on a packed flight could be tough. JetBlue Newsroom
At the time the partnership went public, both airlines made it clear: Blue Sky would operate through an interline agreement. That means each carrier sticks with its own brand and flight numbers, but they can sell seats on each other’s flights. Unlike a codeshare, it’s more about flexibility, but not full integration. Single-ticket itineraries? The companies say those are coming, just not yet.
The airlines plan to continue rolling out the partnership in stages this year. Next up: gauging if travelers actually find the cross-airline booking smooth enough to stick with — and if future phases hit their deadlines.
