Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

I didn’t have a seat assignment and my seat was very dirty on the flight from Frankfurt to Budapest.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.

They cancelled my flight and rebooked for Monday from Saturday without my consent. Putting me in a stressful spot. I have important medical appointments that I can’t miss and work. I tried to contact them to either rebook or request a refund, but I was always 200 or more in line and could never get ahold of customer service the call would always hang up after waiting 2 hours on hold. I’m not sure if I will ever get a refund even though I paid for seats as well, but my only option was to spend more money to rebook with another airline.

Due to cancellation of connecting flight (Lufthansa) I didn’t fly with United

Vegetarian selection could be better. Bread was too hard to chew.

Great until we got to FRA. The next trip leg we were put in Business Class where seats had minimal padding!!!! They were awful and United Airlines needs to have their Lufthansa partner up their game or I won’t fly with them again!!

The wheelchair service is useless. They live you in different spots, not tell you anything just wait. I waited 30 minutes in Frankfurt when decided to walk the 25 minutes distance. In Budapest nobody came.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.
