I've burned close to 2 million miles on AA in the last 5 years, so my redemption hits, to South & Central America, Caribbean, Hawaii and Asia have been excellent, including partner airlines. Delta has its ups and downs, lately I've been able to get direct to Hawaii in F in February 2004 for the wife and I and March 2004 for my mom, but Europe has been tough lately...DL put me on Air France with an extremely bad routing two years ago. US is getting tougher to score F to Europe, lately I have very few Int'l choices on US or partner UA, even as a Chairman's Preferred, but I was able to get three seats in to Paris last year around labor day, row 1 in an Airbus to boot, which was an unexpected plus. This and Flagship 777 in F with wife and mom on AA to Tokyo are probably two of my best redemption values.
