Delta Air Lines is to remove some business class seating in a bid to boost revenue.
The move will see seven seats taken from the B777's current 45-seat business class cabin, to be replaced by 23 economy seats.
Delta's B767s will see a more dramatic reduction — its existing 36 to 40-seat business cabin will lose 12 seats in favour of adding 20 in economy.
The carrier has not specified how many of its B777 and B767 aircraft will adopt the new layout or which routes will be affected
