No, I'm not a big fan of the scent Old Spice, but their disposable Cool Contact towels are great for flying. They come in several different scents (I think "Fresh" is the best as it's the most neutral) and they are substantially thicker than the other moise towelettes that I have seen.

They come in a box of twenty that contains 4 travel packs of 5 towels each. At Wal-Mart they are around 3 bucks a box. (Remember that I'm in AK -- so your cost will probably be lower) and are found near the deodorants, toothbrushes, and that kind of stuff.

Standard Disclaimer: Even though I think these are pretty nifty -- I am simply a satisfied customer and have no commercial interest/connection with the Old Spice company.
