You've got that correct, and it's consistent with BA's message too. But the key point is that BA's fleet size at LGW is a commercial decision, and if the airline chose not to have enough aircraft at LGW to cover an overnight delay on just about their shortest route, then that's their problem to resolve. So I would either ask for a CEDR deadlock letter or go MCOL. I think I'd slightly prefer MCOL, just in case CEDR get too narrow minded, but I think that is unlikely.
