“Dear Partner,
Due to operational reasons, we are allowing customers added flexibility to make voluntary changes to their bookings.
We are allowing customers whose outbound flight, departing from London Heathrow between 14 and 19 December 2022, is still operating, the flexibility to make voluntary changes via the Engagement Centres, or via Travel Agent.
Any connecting BA/BA* flights can also be changed free of charge subject to availability.”
