It's not certain that AA will pay your expenses, but generally they will for BAEC status passengers. So you best be fairly frugal, spending what you would have to pay if it was totally your fault, keep and photo the receipts, then send them in when you're in a position to do so. If you are in no hurry to transfer airports in London, then it's cheaper to take the tube into town and then the Southern from Victoria. Under the Montréal Convention AA is supposed to make good anything in this area but few airlines cover themselves in glory on this one. You may, however, get a voucher from AA by way of customer service remediation.
