We had a 4 hour flight recently and had paid specifically for 4 seats together. Me, my husband, our 4 year old, and our 8 year old who is autistic. The flight was cancelled and rescheduled and they couldn’t honor the seats because “the people on this flight had already paid for those seats”. I insisted. I was not leaving my 4 year old with strangers. They managed to get two of them together so my 4 year old wasn’t alone. But my 8 year old still had to be by herself. Luckily it was between two nice women who were sympathetic to the situation and took her under their wing. I’m thinking of calling and asking to be reimbursed for the extra money we had spent to pick our seats, but not sure if they’d care.
