Travel Troubleshooter: When reserving an extra seat on United, don’t forget to do this
DEAR TRAVEL TROUBLESHOOTER: I booked three nonrefundable airline tickets for my wife and me on United Airlines to fly from Orlando to Rome. United resold the middle seat between us on three of the five flights. I asked for a refund, but United is telling me that I can’t get my money back, since I purchased nonrefundable tickets.

But how can they resell the seats I paid for? I’ve sent emails to the executive contacts for United on your website, but United won’t even give me a travel credit.Can you help me get the $660 back I spent for the extra seat?

ANSWER: United Airlines should have kept the middle seat (that you paid for) empty. United offers the option of buying an extra seat for the same price as your original ticket, if you need more room. This obligates United to keep the seat empty; it can’t resell the seat halfway through the flight.
Your case brings up a long-standing grievance among air travelers. When you have a nonrefundable ticket and can’t make your flight, your airline can resell the ticket, collecting money for the same seat twice. This strikes many air travelers as unfair. In the past, lawmakers have suggested legislating this unfairness and mandating that an airline should refund a nonrefundable ticket if it can resell the seat. But so far, nothing has passed.
