Passengers flying in economy on British Airways’ Boeing 777 aircraft out of Gatwick Airport will be joined by 52 additional passengers by 2018.

British Airways announced the plan to switch from rows of nine seats to rows of 10 at the International Airlines Group's Capital Markets Day last week.

The change will turn a 3-3-3 economy seat configuration into a 3-4-3, and increase the capacity on the aircraft from 280 to 332.

“We are updating our 777 cabins to bring us into line with many of our competitors and allow us to offer even more low fares,” said a spokeswoman from British Airways. “We will begin our refit of the aircraft early in 2018, starting with our Gatwick 777 fleet.”

The update, which would make it possible for British Airways to offer cheaper seats than budget carrier Norwegian on select routes, will also include entertainment systems with larger screens.

Current seat width in economy on the 777s is 17.5 inches, according to SeatGuru. The airline said space in the aisles will likely be tighter due to the addition.

The airline did not confirm whether or not they are considering adding additional restrooms, which could also affect customer comfort.
