The flight (1069) from Norfolk international airport to Charlotte was a very pleasant flight right from the start! Friendly service, no long lines, comfortable seating and a nice cool cabin! / The next flight (#5424) from Charlotte to Des Moines was horrid from the time I stepped on the plane! Hot cabin, hot air, it was like a flying Petri dish! Now im sick and live in a disabled building with elderly people!! Why in God's name would you allow a flight like that to even exist! The plane was a dinosaur! Shame on American Airlines!!
