Lastly, and most importantly, remember to bring your passport, travel papers and some cash. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items can differ between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, knives, fireworks and fuel. Sporting equipment like golf clubs, and items that could harm passengers, such as swords and guns, can't come on board with you either. > > > What to wear on a flight: > > > - Your number one priority is to make yourself as comfortable as possible. Don layers of breathable clothing and don't forget to pack a cardigan in case it gets chilly in the cabin. Opt for flat, well-fitting shoes as your feet may swell a little during the journey.
