United Airlines and JetBlue Airways have announced a strategic partnership named “Blue Sky,” aimed at providing passengers with enhanced booking flexibility and expanded network access.
This collaboration allows travelers to book flights on both carriers’ websites and earn or redeem frequent flyer points interchangeably.
Pending regulatory approval, certain aspects of the partnership may commence as early as fall 2025.
Mutual access to key airports
A significant component of the “Blue Sky” alliance is the reciprocal access to major New York-area airports.
United Airlines will gain access to up to seven daily round-trip slots at New York’s John F. Kennedy International Airport (JFK) starting in 2027, marking its return to JFK since leaving it in 2022.
Conversely, JetBlue will receive additional flight timings at Newark Liberty International Airport, enhancing its presence at United’s primary East Coast hub.
United Airlines left JFK Airport in 2015.
The move was called a mistake by the current CEO, Scott Kirby.
The airline briefly returned in 2021 due to a fall in traffic at the airport due to COVID-19.
United had to leave JFK in 2022 as it could not secure longer-term slots.
Enhanced loyalty program benefits
The partnership emphasizes the integration of loyalty programs, allowing members of United’s MileagePlus and JetBlue’s TrueBlue to earn and redeem points across both airlines.
Preferred status flyers will enjoy mutual perks, including seat upgrades and flexible flight changes.
Airline loyalty programs are increasingly becoming important sources of revenue for airlines.
During the Covid lull, US airlines used these programs for revenue and to raise funds.
United Airlines’ loyalty-related income reached $3.49 billion in 2023, up 10% year-on-year. The Airline increased lounge fees to $1,400 in March 2025.
Operational independence maintained
Despite the collaboration, both airlines will maintain independent control over their flight operations, including scheduling and pricing.
This approach distinguishes the “Blue Sky” alliance from JetBlue’s previous Northeast Alliance with American Airlines, which was dissolved in 2023 due to antitrust concerns.
That wasn’t the only setback United Airlines had received for a partnership.
In 2024, a US federal judge blocked United Airlines’ proposal to buy struggling budget airline Spirit, citing that the deal would take a discount carrier out of the market.
Strategic implications for both carriers
For United Airlines, the partnership facilitates a strategic return to JFK, addressing previous operational challenges at Newark and expanding its footprint in the competitive New York market.
JetBlue, on the other hand, gains increased access to Newark, aligning with its focus on East Coast leisure travel and efforts to overcome post-pandemic profitability challenges.
In the last nine quarters, JetBlue has posted a profit in only two.
The “Blue Sky” alliance represents a significant step in enhancing passenger convenience and expanding network connectivity for both United Airlines and JetBlue.
As the partnership awaits regulatory approval, travelers can anticipate a more integrated and flexible flying experience in the near future.
