Do you have any tips for my flight to Crestwood?
- Air travel can be a pleasure if you bring the right gear. Firstly, you'll want a few basic toiletry items, such as a toothbrush and lip balm, a clean set of clothes and a few magazines. Secondly, make room in your hand luggage for your electronic devices, chargers, any medications and perhaps a proper neck pillow as well. Lastly, and most importantly, don't forget to take your passport, travel papers and some cash.
- Pack all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous products which are explosive or flammable, such as flares, chemicals agents and strong acids, are also restricted.
- The aisles of a plane are no place for a fashion parade. Dress in comfortable layers and pick shoes that are flat, enclosed and easy to slip on and off.
- You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To minimize your risk on board, drink plenty of water, consider wearing compression socks or tights and keep your feet and legs moving.
How to get through airport security fast when flying to Crestwood?
- Keep your boarding pass and passport within close reach. They'll be the first things you'll be asked to show at airport security.
- The X-ray machine comes next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
- All electronic gadgets, including your phone and tablet, will also need to be separately scanned.
- Any liquids or gels, such as shampoo or hand cream, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
- There's a good chance you'll be asked to take your shoes off for scanning, so wearing slip-on shoes is always a wise idea.
- Airlines won't allow any sharp items or pocket knives in your hand luggage. If you need to bring these kinds of items, put them in your checked baggage.
