Delta Air Lines plans to expand its premium economy cabin product to its entire mainline fleet of more than 550 aircraft, on top of more than 250 two-class regional jets.
Called Economy Comfort, the product was rolled out on long-haul international flights earlier this year.
New seats will be installed in the first three to five rows of the economy cabin on all of Delta's domestic Boeing 767, 757, 737, MD-88, MD-90, DC-9, Airbus A320 and A319 aircraft. This will take place as well on Delta's regional aircraft, the Bombardier CRJ900, CRJ700, Embraer E-170, and E-175. Installations will be carried out by summer 2012, said Delta, which will remove a "negligible number" of the current seats.
The new seats have a pitch of at least 34 inches, three inches wider than the current seat pitch of 31 inches on Delta's economy class.
"The breadth of this installation means flights to Canada, Mexico, the Caribbean, Central and northern South America will also offer the Economy Comfort product. The first of these converted aircraft will be a Boeing 757 which will enter service in November," said Delta.
