Secondly, find room in your carry-on bag for your phone and charger, any vital medications and perhaps a proper neck pillow as well. Lastly, be sure to bring your passport, travel documents and your credit cards. > > > Do not pack the following items in your hand luggage: > > > - Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your treasured pocket knife, and products which are flammable or explosive, such as aerosol cans, spray paint and fireworks, are also not allowed. > > > What to wear on a flight: > > > - Go for comfort over style. Prepare for changes in temperature by donning layers, and pick flat, slightly roomy footwear like sneakers. > - Deep vein thrombosis (DVT) can pose a risk on long-haul flights.

They'll be the first things you'll be asked to show at airport security. > - Next up, both you and your carry-on bag must be X-rayed.

Also, they all must fit inside a quart-size (one litre), zip-lock bag. > - The right choice of footwear can save you several precious minutes.
