Using the United Airlines web site, I booked flights using frequent flyer miles (Award Miles). I booked business class - or so I thought - on 6 sectors. The miles for business were deducted and my credit card charged for the relevant amount for business travel. The next day I received an email with the itinerary indicating economy on 4 of the 6 sectors. I called United reservations (why did I bother) and was told I could cancel if I paid for it. My argument this is misrepresentation on the part of United (especially since I can still book 'business' on the website) fell on deaf ears. Any suggestions on what I can do next? Or do I just wear it - realize airlines such as United hate to redeem frequent flyer miles.
