If you’re travelling in a group or a pair, talk to your travel buddy about what you’re both packing so you don’t double up. For example, girls, if you’re travelling with a mate and can’t live without your straighteners, maybe one of you can bring a hair drier and one of you can bring the straighteners (although do consider going au-natural – it’s liberating!)
"Unless you're traveling super long haul, you don't need a $50 neck pillow or $300 noise canceling headphones. Bring some foam earplugs if you want to sleep on the plane, and roll up your jacket for a pillow. Same comfort for a lot less money," says Hester, a writer at Our Next Life early retirement blog, and veteran of "100+ flights a year and 80+ hotel nights."
Most importantly, luggage should err on the safe side of the standard carry-on size -- in inches that means slightly under 22 x 14 x 9 (height x length x width), or 56 x 36 x 23 in centimeters, which is the most common allowable size across airlines. Many bags claim to be regulation size carry-ons and in fact aren't, so double check dimensions before buying to avoid forced gate check.
Invest in Luggage: After you figure out if you will be a “carry-on only” or “check only” type of business traveler, invest in a lightweight, durable piece of luggage that has a warranty. The same goes for a laptop bag. Whether you choose a shoulder bag or backpack, make sure it has a lot of padding and distributes weight evenly. You do not want your luggage breaking in the middle of an airport.
