Firstly, you'll want a few basic toiletry items, such as a toothbrush and lip balm, a clean pair of socks and a magazine or two. Next, find room in your bag for your electronic devices, chargers, any vital medications and maybe a neck pillow too. Lastly, remember to bring your passport, travel docs and some cash. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive.

Sporting equipment like golf clubs, and items that could harm other people, such as firearms and swords, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - The aisles of a plane aren't the place for a fashion parade. Layer your clothing and go for shoes that are roomy, flat and easy to remove. > - The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks or tights. ### How to get through airport security fast when flying to Cosby? > - Have your travel documents and ID easily accessible. They'll be the first things you'll be asked to present to security. > - The X-ray machine is up next. Remove anything metal on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening. > - Electronic devices like laptops and phones will also have to go on a tray for inspection.
