Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Flight was late - I was downgraded from first class to coach

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.

Little warm on the plane and delayed for an hour

Tell the crew (when boarding) to yell at the imbeciles blocking us from walking up to scan. I promise everyone crowds around and half of us (most the time I’m group 4) have to push our way through. Your staff is awesome, the public - not so much-

Bags took over and hour to come out. Delays due to wind caused rebooking.

The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?

Lower WiFi prices; allow us to see our flight on a map; more variety of drink choices.

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

UGH I HAD TO MISS MY FIRST FLIGHT TO TAMPA CAUSE OF THE 10 MINUTE DELAY OF THE ORLANDO TO MIAMI ONE SO THEY HAD ME GET ANOTHER TICKET. I AM NOT HAPPY AT ALL BECAUSE IT MADE ME MISS MY CONNECTING FLIGHT FROM TAMPA TO LONDON AND FORCED ME TO MISS A DAY AT MY ROOM IN THE UK.

Wish they didnt delay off-boarding for 10 minutes so i could connect to my flight from miami to tampa

We experienced gate changes and a long delay. My seat was dirty when I boarded and I had to use wipes to clean it myself. There was an unpleasant and overpowering cleaning product scent on the plane as well that lingered through the flight.
