Do you have any tips for my flight to Williamstown?
- It's easy — first, pack in your passport, travel docs, wallet and medications. Next, you'll want some in-flight entertainment to while away the hours. A thrilling novel and a laptop crammed with your favourite shows are always good options. If you intend to catch forty winks, a comfy neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, squeeze in a few toiletry items so you'll touchdown looking fresh and raring to go.
- Make sure you don't have sharp objects (like a pocket knife) hiding in the bottom of your carry-on luggage. Other prohibited items include flammable or explosive products, such as aerosol cans and bleach, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).
- The aisles of an aircraft aren't the place for a fashion parade. Don comfortable layers and pick shoes that are roomy, flat and easy to slip on and off.
- Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some gentle exercises in your seat to improve your circulation.
How to get through airport security fast when flying to Williamstown?
- Your passport and travel documents will need to be shown to airport security. Have them easily accessible so you don't hold up the line.
- After that, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Items such as your coat, belt and earphones need to go through the machine.
- All your electronic devices, including your tablet and phone, are also required to be scanned separately.
- Any gels or liquids, such as hair oil or hand cream, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
- Slip-on shoes are a sensible footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and other heavy shoes are usually subjected to extra screening.
- Pocket knives and other sharp items can't be taken on board. They'll be confiscated at security, so put them in your checked baggage.
