“Dear Partner,
Due to planned industrial action by UK Border Force, we are allowing customers added flexibility to make voluntary changes to their bookings.
We are allowing customers whose inbound flight arriving at London Heathrow or London Gatwick is still operating, where the ticket has been issued by up to and including the 15th December 2022 and the ticket travel dates are the 23rd, 24th, 25th & 28th, 29th and 30th December 2022, the flexibility to make voluntary changes via the Engagement Centres, or via their Travel Agent.
Any connecting BA/BA* flights can also be changed free of charge subject to availability.”
