United Air Starts Record Fleet Upgrade With Plush New Seats

United Airlines Holdings Inc. is embarking on the biggest fleet rejuvenation in its history, adding widebody aircraft fitted with its latest luxe suites and the longest-range Airbus SE A321 that will link the US with European destinations.

The Chicago-based carrier will take delivery of more than 250 aircraft by April 2028. That includes the A321XLR model that will open routes to smaller cities in Europe and South America, while also upgrading flights with lie-flat seats typically reserved for international service.
