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.

Stranded in Chicago and had to get a rental car, United never took responsibility United said I would be stranded in Chicago for 2 days, no hotel accommodations, sleep and hang out in the airport for 2 days. I had to be in KC for work, so I got a rental car and drove myself to KC. United declined to cover the rental car, and the whole experience was a disaster of customer service. Fly any other airline.

Our flight was cancelled after sitting… Our flight was cancelled after sitting 8 hours at Newark Airport due to plane issues. United could not get us out on another flight for 2 days. We had to drive 8 hours home that night because we had to be home. The issue is they would not reimburse us for our car rental to get home. They offered us vouchers. Why would we spend more money with someone who does not take care of their customers. Our request was for an expense far cheaper than staying in Newark for 2 days. Never again with United. First and last experience

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.

Shockingly bad from start to finish Shockingly bad from start to finish. Rude cabin crew, appalling lack of any service and fithly unattended bathrooms on-board, capped off with 1.5 hours sitting on the Newark tarmac waiting to disembark. "Fly the friendly skies" must be the most ironic slogan in all advertising history.
