Finally, leave space for a toothbrush and some cleansing wipes to ensure you touchdown feeling fresh and raring to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items differs between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like knives, scissors, spray paint and flares. Sporting equipment like baseball bats, and items that could injure passengers, such as pepper spray and guns, can't come on board with you either. > > > What to wear on a flight: > > > - Comfort should be the goal when selecting what to wear on your flight. Consider your choice of footwear with care too, as swollen feet and ankles are quite common. Flat shoes which are slightly roomy are your best bet. > - A serious condition called deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to poor circulation. Doing leg and foot exercises while seated is a great way to prevent this from happening.
