I apologize if this is stupid.... My wife and I are looking at flying out of ORD to PVD on Dec. 23 and then back on Dec. 26. I have the US Air Barclays MasterCard. I looked on US Air Dividend Miles and found a fare for $348 per person. I searched on Kayak and found flights for $283 per person. If I book with US Air over the phone will they match that price? Or would they charge me a booking fee which would (depending on the amount) possibly be counter productive?
