British Airways will expand its winter service between Nashville International Airport and London Heathrow, the airline's second flight expansion from Nashville since it launched in May 2018.

In winter 2019, flights will be offered five days a week, up from four, with service offered Monday, Tuesday, Thursday, Saturday and Sunday.

"The route has proved very popular, and we’re delighted to add this additional service for our customers," British Airways spokesman Chip Garner said.

In 2018, British Airways increased its summer service to seven days a week, the airline's fastest expansion to daily service for a new route in a decade, according to the airlines.

Nashville airport officials have said the British Airways flight to London reached capacity levels in its first five months that were expected in its third year.
