Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

I upgraded to the business class cabin. It was the poorest business class I have ever experienced. No access to any business lounge in Tampa airport. Seats are not comfortable. I had a window seat and had to step/crawl over the next seat. Food was mediocre and service below average for business class. Bathroom location was ridiculous. No place to wait. I cannot believe I paid this kind of money and will never fly Lufthansa Discover again. They really should reimburse me somehow.

Boarding was disorganized. The door to one to the toilets wouldn’t lock. The plane was shockingly cramped, and clearly used for domestic flights due to the menus for items to sell domestic travelers. United should be ashamed of its small seats, tiny unclean toilets, and money grubbing stance toward services, compared to Lufthansa, Emirates, and most international carriers United is awful.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Everything could have been better. What needed to be wrong with United went wrong

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Very good, i got two seats for myself, and was comfortable with the blanket i got

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Flight was canceled. Rebooked on Lufthansa Also Canceled. Had to pay 3000 more per person and fly Alaska to EWR and fly emirates to Athens.

Our flight was cancelled the day before our trip and we we put on a Turkish Airline flight that got us in half a day later.

Everything is smooth without canceling the flight or long delay. We're happy about it.

The flight I initially booked from Los Angeles to Florence. I made sure had a layover of about 90 minutes in Rome, so there’d be enough time to connect. A couple weeks before the flight for some reason I was updated that that flight had changed and I was only gonna have 60 minutes to connect. From LAX we were delayed by 45 minutes meaning making the connection was unlikely. The crew informed me that my connecting flight would not wait and they would rebook me on one four or five hours later. I wasn’t happy, but I accepted it. It is what it is. Except when we got closer, two separate flight attendant approached me eagerly and said they had great news that my connecting flight would in fact wait for me, but I needed to hurry through the airport so they didn’t have to wait too long. I was first off the flight. I ran about 4000 steps. And got through passport control all in under 15 minutes. When I arrived to my gate, I was greeted by a flight attendant there who was completely indifferent, said they didn’t hold the plane and they just closed the doors. Had they even held it for two minutes I would’ve made it. She simply told me that the flight attendant on my flight lied about the plane being held, and that they do it all the time. These were all employees of the same company ITA. I was absolutely livid at her indifference and having been lied to and then having to wait five hours and waste a day in Europe at an airport.

The flight was canceled and we have not received the refund

They lost my checked in bag and have not helped me.

First, ITA lost my bag and the baggage team showed no regard in trying to find it. Second, I had paid for priority boarding as part of a first class ticket and instead they disregarded boarding groups and we all boarded at the same time. Third, wasn't allowed to select my seat in advance even with a first class ticket. When I was assigned bulkhead, I was told I would need to pay to change my seat. Overall, very disappointing experience.

The seats needs to be spruced up , for a long flight very uncomfortable , cushions are worn out but everything else is very good , crew is great.

I guess that was fine with ITA but the Rome airport is so difficult to navigate with so many checkpoints getting new tickets from what was originally given to me

My seat was broken and ducted taped and my monitor did not work the entire time over 8 hrs sitting. And I had no books or anything with me
