Preparing for a cancellation TLV to LHR to YVR and a possible booking on BA to LHR then AA to Dallas on on to YVR. The current flight to Dallas would arrive at the same time the one flight a day that leaves for YVR meaning that I would have to wait for the next flight at 130 pm following afternoon. I cannot leave the airport so does that mean I sit and wait 24 hours for the next flight or...does that make the connection one that BA would not consider. I suppose BA could place me on a different carrier that might be flying directly to YVR such as AC. Would BA try to accommodate me?
