Tix were booked and paid by two different parents and times. Agent relented and waived fee. At the gate we were again challenged and had to go thru it all again. No more United for us!"

Cons: "Confusions on dates from Internet. Your site usually sets its own dates without confirming."

Once the plan took off, the headrest screens asked you to pay some ridiculous amount of money to watch them for the hour that we were on the plan. I wasn't surprised, but I never found out who killed the lady in my show. Bummer."
