United is new to my local airport and I think they are doing a great job. The personnel seem eager to help and all my flights were either on time or early.

The agent at the Orlando airport, Dec. 3, for 3:00 pm flight to Dallas was extremely helpful. The flight out was late, we wouldn’t have made our connection, so she booked a different flight to Phx, then Yuma. Very helpful!

Wish I wasn’t so faithful to united for so many years, they for sure are faithful to nobody... as far as they’re concerns I can just take my two million miles and stick it where the sun don’t shine...

Over an hour to board. I'll never take this flight again.

Gate staff were ill equipped to handle cancellation of previous flight. First plane at gate was ours . Seemed no one knew. It was backed away and previous flights plane pulled in . Waited over a hour when it was announced that flight was cancelled. Instead of moving aircraft to somewhere on tarmac to unload luggage. It stayed there for another hour while our aircraft was waiting to pull back in. Very disorganized. Frontier needs more gates as well. We didn’t appreciate all the fees ...snacks, drinks, luggage etc. we will be going back to Southwest. Frontier should take a lesson on how to run a airline.

Flight attendants expect you to not have a reaction to their controlling and overwhelming attitudes, and if you “talk back” they have you removed from the plane. I personally witnessed multiple people be mistreated and they didn’t say anything because of the fear of being removed from the flight. Also, I was lied to about baggage handlers breaking buckles on a brand new bag I had checked, and merely handed a phone number to call and told the United reps at the baggage claim couldn’t help me with my destroyed bag.

Worst experience

Oct 12, 2019

Not happy that I Missed my flight from Houston to Alexandria because my first flight was an hour and a half late landing in Houston! I ran through the airport to catch my flight and they shut the boarding door as I was running up! They would not let me get into my flight! Had to wait from 9:30am in the morning and finally boarded a flight to get home and see my family at 9:00 pm! I could have drove home instead of flying in the same amount of time! I feel that when they know connecting flights will be late they should call headed and let the other staff member know that someone is running your way! This was the worst experience I’ve ever had with any airline!

United has not shown much in the way of caring for the customer. I teach college marketing and this experience was sloppy at beat.

Jan 8, 2019

Delayed flight. Baggage was delayed didnt get home till 4am because of delayed flight & baggage issues. Staff didn’t even offer one free drink or any snacks. You pay for every tiny thing. They’re close to spirit airlines in my opinion. Won’t be flying them again.

Dec 24, 2018

Was there 45 minutes before flight, it’s Christmas Eve & you told my daughter it was too late , she can’t get on flight.
