It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

On time take off…US cabins look tired and need of refresh!

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

The flight attendant handled a situation in which an angry passenger was demanding to use his own supplemental oxygen equipment firmly but graciously.

Just a crappy airline. The same every time. You feel you are a cow on a farm. You are being being whipped and pulled.
