The long-haul aviation market has transformed significantly in recent years. Airlines are moving away from four-engine aircraft, opting for more fuel-efficient twin-engine jets. Another major shift is the increasing use of narrowbody aircraft on long-haul routes. JetBlue exemplifies this trend with its growing transatlantic network, linking Europe to the U.S. East Coast.
The airline primarily operates its transatlantic flights using Airbus A321LR aircraft, part of the A321neo series. According to ch-aviation, JetBlue currently has 11 A321LRs in its fleet, with nine more on order. Looking ahead, the airline is set to introduce 13 Airbus A321XLRs, though deliveries are not expected until at least 2030, as reported by Travel Weekly. These aircraft feature a dual-class configuration with 24 Mint business class suites and 114 economy seats.
