‍NEW YORK — JetBlue (B6) and United Airlines (UA)  have rolled out the next major phase of their Blue Sky collaboration: starting this week, customers can purchase eligible itineraries operated by either airline directly on JetBlue.com, United.com, and both mobile apps, using cash or loyalty currency (TrueBlue points via B6 channels; MileagePlus miles via UA channels).

For now, the cross-selling applies to “eligible itineraries” operated by a single carrier at a time, but the airlines say they expect to add single itineraries combining flights operated by both B6 and UA later. 

The sales launch follows the first Blue Sky milestone in 2025, when TrueBlue and MileagePlus members gained the ability to earn and redeem across both networks. B6 also says JetBlue Vacations will now include UA flights in Flight + Hotel packages, with cruise products planned for later.

More benefits are in the queue: reciprocal perks (priority boarding, preferred/extra-legroom seating, same-day changes/standby) are expected later this spring, and UA’s MileagePlus Travel is slated to transition to B6’s Paisly platform later in 2026. 

The longer-horizon piece remains United’s planned JFK return/growth, enabled by JetBlue-provided access to slots for up to seven daily roundtrips at JFK’s new Terminal 6 as early as 2027.

Revenue booking is the “make it real” moment for Blue Sky: once flights are shoppable and purchasable in-channel, the partnership moves from loyalty theory to everyday utility, especially for B6 leisure-heavy markets feeding United’s broader domestic/global footprint. 

The next inflection point will be true single-ticket, mixed-carrier itineraries; that’s where customer experience either becomes genuinely seamless—or starts to feel like two separate airlines stitched together.
