Airlines expand premium economy offerings on US-Europe flights

British Airways' Airbus A380 features one seat less, at 55 'World Traveller Plus' seats. These are part of a four-class configuration including first class, business class ('Club World'), and economy ('World Traveller'). The A380 serves routes from London Heathrow to Dallas/Fort Worth, Los Angeles, Miami, and San Francisco.

Some British Airways Boeing 777-200ER aircraft based at London Gatwick have 52 'World Traveller Plus' seats. This configuration allows for more premium economy seating due to smaller business class sections on leisure-focused routes like Orlando and Tampa.

Delta Air Lines offers 48 premium economy seats on certain A350-900s serving routes such as Atlanta to Amsterdam and Los Angeles to Paris under its Premium Select cabin. Virgin Atlantic's Airbus A330-300 also has 48 premium economy seats laid out seven abreast behind the second door.

Virgin Atlantic's next-generation Airbus A330-900 widebody jets offer slightly fewer seats at 46 but still rank among the largest transatlantic premium economy cabins. The airline plans to operate these aircraft on various US-bound routes from London Heathrow and Manchester Airport this February.

Virgin Atlantic highlights benefits such as enhanced luggage allowance, priority check-in and boarding, welcome drinks upon boarding, and pre-ordering options from a bespoke menu for its Premium passengers.
