I did some math and figure I've gotten about $5,000-$7,000 worth of travel from just applying for and using this list of credit cards in the last 6 months. I could inflate it a ton because just two round trips to Hawaii in first class would have run us $5,361 and we are getting them free. But, I wouldn't normally fly first class if I was paying for it. A grand total of 9 roundtrip flights and 10-12 hotel nights. Didn't cost me a dime. Going to do it every year. The British Air deal was probably a once in a lifetime offer though so it won't be this huge every time.
