Do you have any tips for my flight to Washington?
- The trick to having a worry-free travel experience is to be prepared. So, let's start with the basics: passport, travel docs, cash and medications. Next, bring on board items that'll help keep you busy, like some electronic devices or a good book. It's also wise to pack your chargers, a neck pillow and a pair of headphones. Finally, be sure to chuck in toiletry items like a toothbrush, deodorant and a fresh change of clothes.
- Leave all your full-sized bottles of hair gel and hairspray 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. Sharp or pointed objects, like your trusty pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, spray paint and fuels, are also restricted.
- Your goal here is to feel as comfortable as possible. Pick shoes that are easy to pull on and off, dress in loose, breathable clothing and remember to take a pullover in case it gets chilly in the cabin.
- Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.
How to get through airport security fast when flying to Washington?
- Airport security personnel first need to check that you have a valid passport and matching travel documents before you can proceed any further. Have them ready to show.
- After that, both you and your carry-on bag must be X-rayed. To speed things up, take off anything that might trigger the alarms. Personal belongings such as your belt, coat and headphones need to go through the machine.
- For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronic devices must also be sent through the scanner.
- Can't travel without your favourite perfume or cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's OK to bring with you in your carry-on.
- There's a good chance you'll be required to take your shoes off for scanning, so wearing slip-on sneakers is always a smart idea.
- Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won't be allowed on board.
