The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Even though we were delayed, we were able to make our connection

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

It was a short flight. Plenty of room on the plane. It was also extremely clean.

I arrived late in Frankfurt and I had to catch my flight to Vienna and I was running late because when I was landing the flight to Vienna was boarding. I had to go through immigration and then I had to wait in a long line to take a bus to a terminal where my flight to Vienna was taking off. However, I truly didn't think I would make it. I was literally running through the whole airport and when I stopped to ask at one of the Austrian Airlines gates they were rude because they didn't have the time to support me.

They were late and I missed my flight for Chicago. Terrible experience with Austrian airline this time.

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

They separated me from my kids We were checked in to fly from Vienna to Frankfurt and Washington DC final destination but separated my wife and kids sent them to Barcelona instead then Washington DC They end up traveling for 26 hours Horrible experience Never Austrian Airlines/Lufthansa again!

The flight didn’t happen with Lufthansa. It got canceled with no reason given and all I received for my troubles was €20. People make travel plans for a reason and when the flight was rebooked, it was delayed for 4 1/2 hours on Austria Airlines. The flight attendants were of zero help. They just wanted to stand and look pretty. I hope to never fly Austrian Airlines again. Horrible!!

Food selection wasnt great, even for flight meals. However staff was e extremely pleasant

Lost my luggage and still not found to this point.

was having emergency they keep dalying the flight I miss hull my trip and united airline charges me &100 for bags and I spent more thin $320 at airport for my family and when I get back samthing Daly my flight in muc I lost flight in Chicago I spent another &220 at Germany airport for no reason I should get refunded it’s very hard when total off us 7 people buy food at airport

The plain was on time. Better seating, better service than Discover. I wish I could used them for my return flight. I have used them before, and they were always good.
