Wonderful experience! The crew was outstanding and amazing from check in to gate to flight crew! Amazing. Thank you!
Wonderful experience! The crew was outstanding and amazing from check in to gate to flight crew! Amazing. Thank you!
I arrived 59 minutes before the flight in Tampa due to Massive traffic jam and the flight was closed and I was told that I’d simply have to “book a new ticket on line myself and the gate agents couldn’t help me”. Even though the flight was delayed over 30 minutes, (leaving one hour and 29 minutes before departure, they refused to assist in any way explaining that it’s automatic and there can be no exceptions. Horrible experience due to poor management at gate. I fly this option 2-3 times a year and have a good experience with the cabin crew etc. But, Tampa agents are not trained or allowed customer service. I once was a gate agent for USAir, I know times have changed, but forcing me to purchase a new ticket and complete indifference and inconvenience. No thanks
Crew members were good. Seats were packed and too tight .
Carry on luggage size for economy passengers significantly smaller than other airlines, so nearly all ecomy passengers had their bags taken and checked.
Had a short layover in Zurich, luggage marked expedite and short layover but still didn’t get luggage when arrived in Split until 3 days later even though husband got his.
On time flight, I requested wheelchair in Zurich , when I arrived they were no where to be found, I had one hour between flights I had to walk with great difficulty.
Far above average. The level of quality and service has really improved and passed most US carriers on this route. Go Edelweiss!
We had issues with upgrading our seats. The flight itself was fine.
Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!
So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.
The Lufthansa flight was delayed, and I missed the connecting flight. Lufthansa customer service have not been helpful in rebooking the subsequent flight with Air India (another airline that is part of the Star Alliance). Lufthansa told me it's not their responsibility, and Air India says the PNR is part of Lufthansa, so they are not responsible for rebooking. Lufthansa customer service asked me to contact the counter at Delhi airport, but no one was available there. I am caught between these two airlines, and ultimately, Air India decided to reschedule my flight after 18 hours. I am stranded at Delhi airport. I can't go out because if I do, I can't come back in, and I can't get past security to get food. My 3-year-old and our family stranded here for 12 hours without food and water.
I wasn’t able to make my flight due to Kayak’s inability to simply update my name on my trip from Nick to Nicholas. I would like a refund.
The flight left an hour late and no explanation. Food was basically a few snacks out of bags and tiny cup of soda. Crew was pretty friendly.
United delayed the flight to assist customers to make the connection. The Ohara customs area was overwhelm which created an issue for customers trying to make the Little Rock connection. The delayed allow several customers to make the final flight into Little Rock.
Missed our flight to London and we were put on coach seats to Munich.
Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster
They canceled our flight last minute and we had to get another flight with twice the cost
Dinner was excellent - beef stew, the eggs for breakfast were only ok. It was soooo nice that there were so many options for movies and games.
Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.
Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.
