My original flight to BKK through Narita was 3 hours delay which means I would have missed my NRT to BKK flight and some appointments on Friday. Thanks to American Airlines for notifying me early enough for me to call and rearrange. The best part is my wish was granted as I got rerouted on AA 137 traveling to BKK via Hongkong on a 777-300 where everyone gets the aisle seat! Love it! Going to be a longer flight on first leg too so make it more worthwhile to request for upgrade.
