Never had such a lazy first class attendant. Literally spent 60%+ of the flight playing games on her personal phone making up excuses of why she was unavailable.

Never had such a lazy first class attendant. Literally spent 60%+ of the flight playing games on her personal phone making up excuses of why she was unavailable.

The flight attendants and the service is getting worse by the day.

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

Like all of the flights I took to get down to Dallas. They were delayed

Other than nearly three hour delay for maintenance issues, everything went smooth

Plane from partner PSA was filthy. Plastic needs to be thoroughly cleaned. Really disgusting to look at and wonder about cleanliness of parts less visible.

The baggage claim experience was poor. The plane crew and the AA app said that checked baggage in CLT would be at carousel 7 but the sign at Baggage Claim said carousel 1. The carousel 1 sign had the correct flight # listed above the belt. But the luggage never came. I went to an AA baggage claim office after about 1 hour and the clerk directed me to another AA room that was poorly marked, with a closed door and no obvious way to know what to do. Finally someone opened the door and my bag was inside. The clerk was totally unable to explain why.

They are rarely on time! Very hard to plan your travels when flights or connections keep getting delayed.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.
