The entertainment wasn’t playing in the app or online.

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

They have trouble to keep their flights in schedule. Seems not having enough staff to provide appropriate customer service. Lacking real agents on site to help customers. Have to use QR code/web site/call to be able to talk to real person can help you - and you may have to punch though series of options first, then hold until someone assist you. Similar for baggage claim, no real agent onsite helping if you missing luggage, not like other airline next to UA desk having staff there even after midnight to assist customers.

United is my favorite and I always try to fly United. I feel like this crew didn’t mesh well together.

Our flight was delayed three times. It took us 17 hours to get home.
