I had the double misfortune on a recent flight from LAX to BOS of missing my first upgrade in almost three years and having someone who needed two seats sitting next to me. I literally spent about 80% of the flight standing as it was miserable trying to sit next to someone who took up his seat and half of mine and did not even try to squeeze into only his seat. The flight attendants seemed to take pity on me and suggested that I contact customer relations when I had the chance. I did so three days after the flight and they immediately offered me a $300.00 travel voucher or 20,000 miles. I opted for the miles and they were in my account the next day. Once again, AA has proven to me that they truly care about their customers.
