Has anyone else been surprised to learn (after buying tickets) that the fare-drop-credit they advertise is actually a voucher (good for a year, limited to $100)? We bought tickets to Paris for next summer for our son's family (5) and chose Cheapair because of their price drop payback policy: "If fares drop after you purchase, we'll credit you back the difference." This is what appears on their booking page. Well, when I read the terms and conditions, I learned that the credit was actually a voucher toward a future Cheapair ticket in the name of the passenger (not transferrable), limited to $100. Further, the onus is on the purchaser to check Cheapair's site daily or weekly or whatever to see if the fare drops! So, if you're buying tickets for family members who don't fly often, this is virtually worthless -- and if you buy for yourself, you have to book your next ticket on Cheapair AND check often to see if fares drop. Also, when we tried to change seats online thru the airline, we were given the message that we needed to go through our travel agent (Cheapair), but only after selecting all the new seats and submitting for confirmation. A phone call to Cheapair took care of it, but only after a lot of wasted time on websites.
