Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

It was a short flight so I was expecting too much

Both of my flights arrived early and check in process was smooth

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.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Flight home lot's of room shame I never noticed that they ripped my suitcase and didn't notice it to I got toy destination and had to buy new set

flights were on time, boarding was easy. maybe better snack selection, like mini kind bars?.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

Ridiculous delays with weak excuses. United needs to do their job and troubleshoot. The rate they charge demands no less. Planes are way too full and seats are cramped. Charging for seats and luggage adds insult to injury.
