For the Delta Skymiles and/or AA discount codes you posted, will I need to show a freq flyer membership card or something? I haven't carried a membership card in years except for when I have elite status, so I wouldn't have the foggiest clue where I'd find mine.
It'll only save me a whole 2.5% on my rental over my corporate rate, so I guess I don't care either way, but its always nice to save $3.
peace,
