Finally, don't forget to chuck in toiletry items like a toothbrush, deodorant and a spare change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Double-check that you don't have a pocket knife lurking in one of the compartments of your carry-on luggage. Other banned items include explosive or flammable goods, such as aerosol cans and bleach, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters). > > > What to wear on a flight: > > > - The answer to a comfortable flight can be as simple as your choice of clothing. Prepare yourself for varying temperatures by layering up. That way you'll stay nice and warm if the cabin gets chilly. Shoes like high heels and sandals are best left in your suitcase.
