British Airways is moving many of its flights operating out of Heathrow airport’s Terminal 3 to Terminal 5.
All of the carrier’s long-haul flights, and over half of its short-haul flights will operate to and from Terminal 5 from July 12.
The airline stated that “the move will help increase operational resilience for our flying programme and improve the experience for customers with connecting flights”.
British Airways has begun informing customers via email and recommends that passengers check their booking on its website before travelling.
Last week the airline’s workers based at Heathrow voted in favour of strikes in the second half of July.
The dispute is about the 10 per cent pay cut the staff agreed to during the pandemic and future pay.
