Yes. United and JetBlue customers can book eligible flights operated by either airline through either carrier’s website or app, subject to availability. You can pay with cash or, on the booking airline’s channels, use its own loyalty currency: TrueBlue points on JetBlue or MileagePlus miles on United. Blue Sky is an interline agreement, not a codeshare, and a single itinerary combining both airlines was described as a future feature in the February 2026 announcement.
Can I book a United flight on JetBlue, or a JetBlue flight on United?
Yes. United and JetBlue announced on February 10, 2026, that customers could begin booking eligible flights operated by either carrier through either airline’s website or app. The rollout was phased, and availability is not guaranteed: the airline operating a flight controls its inventory, and fares can change. JetBlue’s announcement and its Blue Sky FAQ describe the booking arrangement.
Search on the website or app where you want to make the purchase, then confirm the operating airline and the fare details before paying. A flight appearing on one carrier’s channel does not mean every flight or seat is available there.
Can I use United miles or JetBlue points?
Cash bookings are available. For award bookings, the February 2026 announcement identifies TrueBlue points on JetBlue channels and MileagePlus miles on United channels. In other words, the booking channel determines which of those two currencies is named for the redemption; the announcement does not say that you can use either program’s currency interchangeably on both airlines’ channels. Check the award price and terms shown at checkout.

Is Blue Sky a codeshare?
No. United and JetBlue describe Blue Sky as an interline agreement. They continue to market flights under their own brands and flight numbers; it is not a merger or a unified operation. The February 2026 release said that a single itinerary combining flights operated by both airlines would be added in the future. The launch announcement therefore does not establish that customers can already book a mixed-carrier itinerary as one ticket through the new feature.
Will I earn loyalty rewards on the other airline?
The booking announcements establish which points or miles can be used on each airline’s own booking channels, but do not establish the earning rate or eligibility for earning rewards on every cross-booked flight. Review the applicable loyalty-program terms for the specific ticket rather than assuming a flight earns in the program associated with the booking site.

What reciprocal benefits can eligible members receive?
In a May 14, 2026 announcement, JetBlue described reciprocal benefits for eligible members who add their frequent-flier number to the reservation. The listed benefits include priority boarding, complimentary access to extra-legroom seats at check-in, priority check-in and security, preferred seat selection after booking, one free checked bag with priority handling, and same-day standby options. The specific benefit can vary by member tier and operating airline, and terms, conditions, and exclusions apply. See JetBlue’s reciprocal-benefits announcement for details.
Who handles seats, bags, special services, and disruptions?
For seating, special services, baggage policies, and trip management, JetBlue directs customers to the airline operating the flight. Check that carrier’s rules for the specific itinerary before purchasing. JetBlue’s FAQ says a single ticket protects customers in the event of unplanned disruptions; because a mixed-carrier single itinerary was described as a future addition at launch, do not assume a separately booked combination has that protection.
