Blocking the aisle during boarding while you dig for gum, a book, a hand-held computer game, disinfecting wipes, or earphones will annoy your fellow passengers -- and can delay the departure of your plane.

To avoid this, pack these small must-haves in a resealable gallon-size bag (or any small, easily grabbed "day bag") and place it near the top of your carry-on bag. This will make the bag and its contents easy to retrieve as you take your seat.

Bonus: you'll have a convenient place to stow these necessities during flight and reduce your chances of leaving something behind.
