JetBlue Airways is the hybrid carrier - low-fare-first with surprisingly nice touches the legacies still don't bother with: free Fly-Fi Wi-Fi, free seatback TVs, generous economy seat pitch, free snacks (yes, the blue chips). In 2025-2026, JetBlue is layering a more premium experience on top - BlueHouse lounges, Mint Europe expansion, the new Premier credit card - without abandoning the everyday low-fare base. JFK is JetBlue's primary hub; Boston, Fort Lauderdale, Orlando, San Juan, and the LAX/LGB pair are focus cities. The Spirit merger is dead - a federal judge blocked it in court, the carriers terminated the agreement, and Spirit ceased all operations on May 2, 2026. JetBlue is solo and pivoting toward premium.
The big 2025-2026 stories are Blue Sky with United and the Mosaic overhaul. Blue Sky is the multi-phase reciprocal partnership that replaced the dead AA Northeast Alliance. Phase 1 went live October 23, 2025 with reciprocal earning and redemption between TrueBlue and MileagePlus, so you can spend TrueBlue points on United-operated flights and vice versa. As of May 2026, eligible Mosaic members also get reciprocal United perks: preferred or extra-legroom seating, priority boarding and check-in, one free checked bag, and same-day standby. The big asterisk: Blue Sky still does NOT include complimentary upgrades, elite-status credit, lounge reciprocity, or status matching. Mosaic 4 still can't enter a United Club, Premier 1K still can't get into BlueHouse, and the two programs keep separate balances. The Mosaic overhaul (effective February 1, 2026) restructured elite tiers into Mosaic 1/2/3/4 (50/100/150/250 tiles), introduced family tiles that count kids age 12 and under toward the listed adult's status earning (1 kid = 2x earning speed; 2 kids = 3x), and stripped some perks at the bottom (Mosaic 1 dropped from 2 free bags to 1).
What still makes TrueBlue worth knowing: points don't expire, Points Pooling lets 2 to 7 members pool with no relation requirement (genuinely consumer-friendly - not gated to immediate family like other programs), and award pricing is fully revenue-based with no fuel surcharges on JetBlue-operated flights. The flexible-currency on-ramp is among the broadest of any US program - Chase UR, Citi TYP, and Wells Fargo Rewards all transfer 1:1, while Amex MR transfers 1:0.8 and triggers federal excise tax pass-through since JetBlue is US-domiciled. Add in Mint (lie-flat business class on transcon and transatlantic routes, with Barcelona launched April 2026 and Milan in May 2026), the new BlueHouse lounges (JFK open since December 2025, Boston mid-2026), and the brand-new Points On Repeat subscription tiers (launched March 31, 2026), and TrueBlue is one of the more interesting US programs to learn in 2026.
