JetBlue Airways Corp. and United Airlines have expanded their Blue Sky collaboration. The partnership allows customers to book eligible flights operated by either airline directly on JetBlue’s and United’s websites or mobile apps.

Beginning this week, travelers can purchase flights using cash, TrueBlue points or United MileagePlus miles across both networks. This offers customers more flexibility in how they search, book and pay.

Flight results on each airline’s platform will now display more options from both carriers. The airlines said they plan to eventually allow customers to book single itineraries that combine flights operated by both JetBlue and United.

“With cash bookings now available, Blue Sky is making it even easier for customers to plan and purchase travel across two leading networks,” said Andrew Nocella, executive vice president and chief commercial officer at United. “This milestone is another proof point of the value Blue Sky is bringing customers – in giving them the ability to book with cash, miles or points on either network, customers now have more choice, flexibility and a better overall booking experience when traveling to their favorite destinations.”

More to come

The update builds on the 2025 launch of reciprocal loyalty earning and redemption between the two carriers.

“This is an important step forward in our Blue Sky collaboration, expanding the choice and flexibility we offer customers when they travel,” said Marty St. George, president of JetBlue. “This move gives our members even more ability to earn and redeem points to exciting destinations around the world, while United customers gain access to JetBlue’s network across the Americas and Europe.”

Additional enhancements planned later this year include reciprocal loyalty perks, such as priority boarding and preferred seating; United’s MileagePlus Travel platform transitioning to JetBlue’s Paisly travel services platform; and United’s planned expansion at John F. Kennedy International Airport Terminal 6, where JetBlue will provide access for up to seven daily roundtrips starting as early as 2027.

United operates from Terminal C at Newark Liberty International Airport. JetBlue offers service from Terminal A, with international arrivals landing at Terminal B.
