Got a booking at end of June for biking weekend in Switzerland. Booked flights with BA.

They’ve just sent an email cancelling the return flight but not the outbound.

Are they trying to pull a fast one?

Is this a ploy to get me to either change flights and accept their voucher or cancel and they keep the outbound flight money?

Did you buy two separate flights or one product of a round trip?

They can just cancel one, it might only be the early flight of each day that’s cancelled. If it’s on one ticket you’re entitled to a full refund, if you booked them separately You’re on your own

One round trip. Bought at the same time on the same booking.
