I would have to say the best "steal" was due to a little special AA was running in the summer of 2001. Fly 4 segments and get a 2500 mile bonus, 6 segments gets a 5000 mile bonus, 8 segments gets 7500 mile bonus, and finally 10 segments got a 10000 mile bonus.
So, for $110.00 each, I bought 4 PHX-LAX-SAN-LAX-PHX round trips. 370 to LAX, and 109 from SAN. Minimum 500 each leg, plus PLT 100% bonus, plus 1000 miles booking online, plus the above mentioned special they were running.
For 4 roundtrips, I travelled 3832 actual miles, but racked up 45000 miles, all for $440... which works out to $0.0097 per mile.
