Earlier this year, I flew to Brussels twice for about the money you are talking about and got close to the miles you are talking about and I got two trips to Europe!!!( AA ) All you are doing is buying miles, and spending a whole day doing in. I don't think it is worth it if you don't really want to go to where you are flying. I will get close to 40,000 miles on my upcoming trip to London (on AA) and the fare cost me about $275 (using a voucher which waived the tax and volumebuy certs which gave me 25% off) and I get to have a vacation in London. Yes, the mileage possibilities got me looking into this trip NOW, but would I fly to Londong and immediately return just to get the mileage? Hell no.
