If it's not a stupid question, what did the captain say was the cause of the delay? If it wasn't weather or some such then you can go ahead with MCOL, or potentially ADR, since the deadlines will be enforced by the respective deadlines. It will be up to BA to provide the relevant proof by those deadlines.
The only thing that the captain said was late inbound aircraft.
I'm sorry but there is something odd if I am told by BA that weather was the issue but then later told they don't know what caused the delay. That's either incompetence or an attempt to fob me off. I had a similar experience with changing reasons on a previous claim.
