Do you have any tips for my flight to Security?
- The trick to having a pain-free travel experience is to be prepared. Start with the essentials: passport, travel docs, credit cards and daily medications. Next, take on board items that'll help keep you occupied, like your laptop or a thrilling book. You'll also want to bring your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to pop in toiletries like a toothbrush, lip balm and a clean T-shirt.
- Check carefully that you don't have sharp objects (like a knife or scissors) hiding in your carry-on luggage. Other restricted items include explosive or flammable goods, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).
- Comfort should be your top priority when deciding what to wear during your flight. Loose, breathable clothing is a wise choice, as are enclosed shoes like sneakers.
- 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 and move your legs and feet often.
How to get through airport security fast when flying to Security?
- Be sure to keep your ID and boarding pass close by. They'll be the first things you'll be asked for by security.
- The X-ray machine is up next. Remove anything on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
- Your electronic gadgets like laptops and phones will also need to go on a tray to be scanned. Don't worry though, you'll be back online soon enough.
- Any gels or liquids, such as perfume or hand cream, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
- Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and heavier-style shoes are often subjected to additional screening.
- Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed in the cabin.
