Do you have any tips for my flight to Saint Louis?
- It's simple — first, pack your passport, official ID, bank cards and medications. Next, you'll need some in-flight entertainment to while away the hours. A thrilling novel and a phone filled with your favourite movies are always good options. If you plan to catch up on some sleep, a comfy neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some cleansing wipes to ensure you arrive at your destination feeling fresh as a daisy.
- Double-check that you don't have sharp objects (like a knife or scissors) hiding in one of the compartments of your carry-on luggage. Other prohibited items include flammable or explosive products, like aerosols and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).
- Your main priority is to be as comfortable as possible. Choose easy-to-remove footwear, dress in loose, breathable clothing and remember to take a sweater in case you get chilly in the cabin.
- Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clotting due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.
How to get through airport security fast when flying to Saint Louis?
- Airport security personnel first need to establish that you have a valid ID and boarding pass before you can proceed any further. Have them ready for inspection.
- The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
- For just a few moments, you'll have to unplug from the digital world. Your phone, laptop and any other electronics will need to be sent through the scanner.
- Any liquids or gels, such as shampoo or hand cream, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
- It's also possible you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a wise idea.
- Airlines won't allow any sharp objects in your carry-on luggage. If you need to bring these kinds of items, put them in your checked baggage.
