Booked a trip in December with the family and found out they have several levels of classes for the flight which all have different restrictions. Very confusing and why do you need more than two classes ( First/business class and coach). Then we paid for our seats to be able to sit together and then two days before the trip they moved our seating and separated us. They also said we could prepay for check baggage. Called to figure out why and they said the flight changed and others on the other flight also booked those seats when the flight changed and with our class checked bags had to be purchased at the gate. WTH we purchased our seats way in advanced and not my issue it is united and they need to fix. After several calls and three supervisors later, still not resolved except we were able to prepay for checked luggage. Oh the last supervisor said there was no one above them to talk to. REALLY? Even the CEO has to answer to the board members so let us not go there and keep lying. United is off the list for good customer service. read more
