- Wet or Purell wipes, and lots of it.
- Small Tupperware to save leftovers.
- Enough socks plus some for commute.
- Exofficio boxers (breathable, washable, quick drying)
- More Purell wipes
- Spare shirt, spare slacks.
- workout clothes
- tide pen
- single load laundry detergent
- more wipes
- vacuum seal bags for lots and lots of extra luggage space
- sudoku book
Seriously though - cockpits and hotel rooms are gross. Wipe that **** down. As for the boxers I mentioned, I bring only 2-3 pairs for even a 4-5 day trip. Look them up.
