The United and JetBlue Blue Sky partnership is live for earning, redeeming, booking on each other's websites, and a set of reciprocal perks for status members. A single ticket that combines both airlines is still to come, and so are the JetBlue slots at JFK that United will use.
What's Live Now
The partnership has rolled out in three steps. On October 23, 2025, TrueBlue members could earn and redeem on United flights, and MileagePlus members could do the same on most JetBlue flights. On February 10, 2026, the two airlines began selling each other's flights on their own websites and apps, for cash, TrueBlue points or MileagePlus miles. The reciprocal perks started the week of May 14, 2026, with priority boarding, extra legroom seating, and same-day standby among them.
Two pieces are still ahead. JetBlue has said travelers will eventually be able to buy one connected ticket that mixes both airlines, with no date given. Today, connecting itineraries that mix JetBlue and United flights aren't allowed, so each airline needs its own booking. JetBlue also plans to give United access to slots for up to seven daily roundtrips at JFK's new Terminal 6, beginning as early as 2027.
How Earning Works, and Where the Asymmetry Sits
Earning is generous on both sides, but the credit toward status is not symmetrical.
TrueBlue members flying United earn 5 points per $1 of pre-tax fare and carrier-imposed surcharges. Mosaic 1 and 2 members earn 8x, Mosaic 3 earns 9x and Mosaic 4 earns 10x. Tiles accrue at one tile per eligible $100 spent, the same rate as on JetBlue flights, so flying United moves a JetBlue loyalist toward Mosaic.
MileagePlus members flying JetBlue earn 5 miles per dollar before Premier bonuses, but JetBlue-operated flights don't earn Premier qualifying points or flights. A United loyalist who switches to JetBlue for a transcon earns redeemable miles and nothing toward status. Some JetBlue routes are excluded from MileagePlus earning altogether, including Newark to Cancun, Aruba, Los Angeles, Las Vegas and Punta Cana, and earning is limited to select fare classes.
The practical translation: the partnership rewards JetBlue loyalists who fly United more than it rewards United loyalists who fly JetBlue. If you're chasing Premier status, JetBlue isn't the answer.
Award Redemptions: Check Both Sides
You book awards through your own airline's website by choosing to search with points or miles. Seats are capacity-controlled, so availability on high-demand flights is limited. JetBlue prices awards against the cash fare, so price the same flight with TrueBlue points and with MileagePlus miles before you commit, because the better price can sit on either side.
Know the limits before you book. TrueBlue points can't transfer to MileagePlus, and this isn't a codeshare. An award booking can't be changed once made: you can cancel before the first outbound departure, the points return to your TrueBlue account, and the taxes come back as a JetBlue travel credit. You can't put both a TrueBlue and a MileagePlus number on one reservation, and Cash + Points isn't available on United flights.
Perks: What's Included and What Isn't
The perks JetBlue lists for Mosaic members flying United are priority check-in and security, priority boarding, extra legroom at check-in (Economy Plus on United), a preferred seat after booking, one free checked bag with priority bag handling, and same-day standby. Mosaic 1 and 2 board in Group 2 on United, and Mosaic 3 and 4 board in Group 1. United Premier members get matching perks on JetBlue, including priority boarding by tier and EvenMore seating at check-in.
The terms matter. You have to add your loyalty number to the reservation, only the highest-status member's perks apply on a booking, and checked bags and paid seats are bought at united.com when you fly United. Mosaic perks don't extend to other Star Alliance airlines, and Perks You Pick selections don't apply to United. Lounge access and complimentary upgrades are not among the listed perks.
A Flyer's Playbook
For a TrueBlue loyalist, the partnership is a net upgrade. United's network fills the holes in JetBlue's route map, the tiles come with you, and the earning rate on United flights is strong. Use it.
For a MileagePlus loyalist, the calculation is narrower. JetBlue makes sense when it has the better schedule, the better price, or a nonstop where United connects, and you treat the miles as a bonus rather than a path to status. If you're working a Premier qualification year, stick with United flights. If you're status-agnostic and want the most efficient routing out of the Northeast, JetBlue is now a usable option without leaving your United account behind.
For award bookings, compare both currencies on every routing.
What to Watch Next
Three things are worth tracking. First, the single connected ticket that would let you mix both airlines on one itinerary. Second, whether lounge access or upgrade reciprocity ever joins the perk list. Third, the JFK Terminal 6 slots for United, which JetBlue has said could begin as early as 2027.
If you fly both airlines, add both loyalty numbers to every Blue Sky booking and price awards in both currencies before you book.
