Iberia has confirmed the first four routes will feature its new premium economy product later this year.

Bookings are now open for premium economy seating on flights to Chicago and New York (starting in May), Miami (from August), and Boston (September).

Iberia is in the process of retrofitting the new seat onto 21 long-haul aircraft during 2017 and 2018 – eight A330-300s and 13 A340s. A further 16 A350s will be factory-fitted with the new product, when they are delivered “after 2018”.

The IAG member carrier announced its new premium economy seat in October last year, with features including a seat width of 19 inches (11.6 per cent more than in economy), a pitch of 37 inches (20 per cent greater than economy), 40 per cent more recline compared to economy, and a larger IFE screen (12 inches compared to nine in economy).

Other features will include adjustable head and foot rests, noise-cancelling headphones, and an “exclusive amenities kit”. Premium economy passengers will also benefit from priority boarding and disembarkation, an extra suitcase allowance, upgraded dining options and “other privileges”.

Commenting on the new seat Iberia’s chief commercial officer Marco Sansavini said:

“Our customers have a variety of preferences and priorities, and Iberia is adapting in order to meet all those needs. The new Premium Economy is designed to reach a new kind of traveller who seeks enhanced service before and during international flights, but does not wish to elect for business class.

“Our fares in the new intermediate class will appeal to a wide cross-section of customers, and the new class of service will be ideal for special trips and celebrations.”
