I checked a bag and there was only one agent to assist all customers with any issues.

I checked a bag and there was only one agent to assist all customers with any issues.

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

The flight left over 2 hours late and caused me to miss my connecting flight. Consequently, I missed my cruise ship out of Barcelona. The cost associated with this miss was as follows: Airfare to Sicily Italy to get on the ship TWO days late - $232.30 Taxi from Airport to hotel $35 Dinner at hotel $38 Hotel in Barcelona - $208 Taxi from Sicily to hotel $70 Hotel in Sicily - $148 Prorated time missed on cruise $ 1,143

Made me check my carry on and then lost it,

The flight ran out of hot meals for the back half of the plane and gave us tuna sandwiches. Not okay, these flights cost too much to short us the experience!

This was a bare-bones flight on a small plane. I chose it for the good fare and the fact that it was nonstop. No entertainment and just beverage service were fine on this short haul.

Our plane was so cramped that I couldn’t fit my bag below my feet and my knees were pressed against the seat in front of me. For a 45 minute flight, We sat on the runway for over an hour before returning to the gate to wait for another 2 hours. We arrived over 4 hours late, uncomfortable and tired.

Being forced to listen to commercials before and after takeoff, being charged for every little thing, in flight entertainment that doesn’t work, on and on.
