Always an issue I hade at least 5 hours of delays for a flight out of buffalo to newark. an aircraft never left and after switching my connection flight twice, was told it was being taken out of service. another plane was going to be sent from Chicago, to arrive after my last connection flight was scheduled. there way no way for me to get to any connection. I was set up with flight following day. we were an hour late getting off ground and we arrived in Washington fifteen min before my connection. I got off fast and shuttled to other side of airport and ran to gate. the flight was supposed to leave at 8:15a and I arrived to gate at 8:19 to find the plane left earlier than scheduled. now I'm stuck again for five hours before I can get home or continue to ny original destination. always have issues with United.

Baggage was delayed and they closed my… Baggage was delayed and they closed my case after I got the baggage. They dont answer because of interim expensives. Really bad airline. Dont book.

Awful Booking Process and Customer Service I haven't even flown with United yet, but so far they've made me re-book my flights 3 times, and there's still another 3 months before I fly. I booked a return flight to the US from the UK in January, I went on-line in March to check some details to find that my flights had been changed and my seat upgrades had been cancelled with no refund. So I re-upgraded and chose new seats, a month later I checked again, the flights had changed again, still no warning or refund, so yet another, re-select the seats and pay the upgrade fee again, 1 month later, same thing. Each time I re-upgrade my seats my bank charges me £1.50 for each transaction (United put each seat on each flight through individually from the US whereas the original booking was taken from the UK). In terms on transaction costs alone I'm down around £18, if you add to that the fact that not a single cancelled seat hasn't been refunded then it's around £250. I feel a small claims court action coming on.

First Flight, Last Flight. Aside from the recent scandal United Airlines is literally the worst airline I've ever flown with. The only impressive this is how consistently bad they are at literally every area that constitutes a good flight experience. Incompetence like that takes dedication. Hats off to you United, I will never be flying with you again.

Terrible service for premium Polaris… Terrible service for premium Polaris price. ORD to LHR for over $6000. Seat changed twice due to aircraft changes, they claim. Seems to me it’s not rocket science to have an algorithm that maintains seating choices and preferences when aircrafts change? Bag drop off also a pain. Then to the Polaris longe seated lunch? No spaces available, sorry. Terrible all around. Waste of money. Premium price for ordinary service or even poorer.
