Next, throw in some extra in-flight entertainment to while away the hours. A good read and a tablet filled with your favorite movies are fantastic options.

Anything explosive, flammable or sharp is generally not allowed in your carry-on bag. Be sure to pack any sports equipment like tennis rackets or baseball bats in your checked luggage.

What to wear on a flight:

  • Go for comfort over fashion when flying. Layer up and wear natural materials as they allow air and moisture to pass through and keep you cool. Cabin temperatures can get cold on long-haul flights, so bring a pullover and always wear sneakers or enclosed shoes.
