Thanks for this.

Unfortunately MMB did not proactively offer a flight on a new date (in which case I agree about not accepting it and waiting as the seat is secured), it required us to manually search for flights on the next available date which turned out to be Thursday. The risk of not choosing Thursday was that they would then have to travel even later and they have to be back for work.

My comment regarding the common sense of the policy allowing the customer to come home sooner if space becomes available was that it also reduces BA’s liability for eg hotel costs
