United to return to JFK in coming years.
Two major U.S. airlines are joining forces in a blockbuster partnership. United Airlines will team up with JetBlue in a new alliance they are calling “Blue Sky,” the carriers announced Thursday.
The alliance will include a full-blown loyalty partnership that will allow United MileagePlus and JetBlue TrueBlue members the ability to earn and redeem miles on either carrier. Plus, United Premier elite members will be able to enjoy their status benefits when flying on JetBlue. JetBlue’s Mosaic members will get the same treatment on board United.
As part of the new arrangement, United and JetBlue will also be able to sell each other’s flights on their own websites, including connections between the two carriers

✈️ Blue Sky: An Outline of the Alliance
In late May 2025, United Airlines and JetBlue Airways formalized a new strategic alliance named Blue Sky, marking a pivot in both airlines’ Northeast U.S. strategies . This collaboration is not a full merger or joint venture; it’s an interline and loyalty program partnership that shares seat inventory, websites, apps, frequent-flyer perks, and airport slot-swapping, yet preserves each airline’s operational independence .

🛫 What Blue Sky Offers Travelers
1. Unified Booking & Broad Access
Travelers will be able to search and book flights operated by either airline—JetBlue bookings via United’s channels and vice versa . This offers passengers more route options and simplified planning.
2. Earning & Redeeming Miles
United’s MileagePlus and JetBlue’s TrueBlue members will earn and redeem miles across both carriers on most flights, with reciprocal benefits like priority boarding, free checked baggage, and preferred seating .
3. Elite Status Perks
Elite flyers on one airline can access perks—upgrades, same-day changes—on the other. While finer details are still pending regulatory approval and forthcoming announcements, targeted launch is slated for fall 2025 .
—
🏙️ Slot Swapping and New Routes
JFK: United is set to return to JFK with up to seven daily round-trip flights by 2027, utilizing slots granted by JetBlue .
Newark: There will be an exchange of eight flight-time slots, enabling JetBlue to expand its Newark presence while helping United optimize operations .

💼 Strategic Motivations
United Airlines
Re-entering JFK: United exited JFK in 2015 due to unprofitability and did not resume services in 2022. CEO Scott Kirby has long pursued a comeback at JFK to strengthen access to corporate and leisure travel markets .
Mitigating Newark pressures: Newark’s capacity and air-traffic issues have hampered United. Blue Sky helps diversify New York-area operations and reduce reliance on one hub .
JetBlue Airways
Bolstering profitability: After its merger with Spirit fell through and the Northeast Alliance with American was blocked, JetBlue refocused on East Coast leisure markets. This alliance supports network reach and strengthens TrueBlue’s appeal .
Competing with legacy carriers: Aligning with United gives JetBlue more clout in corporate travel and an edge against Delta and American .
—
⚖️ Why It’s Not a Merger
Despite rumors of consolidation, neither airline is pursuing a merger or revenue-sharing structure:
Corporate filings: United explicitly denied merger talks in Q1 2025 filings .
Regulatory navigation: The deal is structured as an interline partnership, avoiding a full codeshare or joint venture—unlike JetBlue’s antitrust-troubled attempts with American.
Operational autonomy: Both airlines will retain pricing, schedules, and network decisions, maintaining independence .
—
👨✈️ Leadership Backing & Competitive Positioning
Scott Kirby (United CEO) lauded JetBlue as “the opposite of other low-cost carriers,” citing its customer-friendly model despite his critical stance on discount airlines .
Joanna Geraghty (JetBlue CEO) described Blue Sky as a clear win for customers, giving TrueBlue passengers access to United’s global reach .
This alliance positions both carriers to better compete with U.S. airline heavyweights like Delta and American by increasing network flexibility and customer options.
—
🛑 Challenges & Regulatory Scrutiny
Antitrust Context
JetBlue’s previous Northeast Alliance with American was struck down in 2023 for reducing competition. Their merger with Spirit also failed in 2024 on similar grounds .
Blue Sky bypasses these pitfalls by avoiding revenue-sharing and schedule alignment, sidestepping antitrust restrictions.
Approval Roadmap
Elements roll out as early as fall 2025, contingent on regulatory sign-off .
JFK flights launch only after slot clearance and airport authority approval.
Customers should expect a phased implementation, beginning with loyalty links and booking integrations, followed by full slot swaps and reciprocal benefits.

Partnering enhances JetBlue’s footprint beyond leisure markets, adding credibility and reach.
Pressure on Delta & American

🌟 Final Take
Blue Sky is a thoughtfully calibrated partnership. It leverages complementary strengths—United’s global scale and JetBlue’s East Coast presence—without triggering regulatory backlash.
