Do you have any tips for my flight to Washington?
Depending on where you're coming from, your trip to Washington could be a breeze or it could drag on forever. We've pulled together some useful hints that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • First, pack your passport, official ID, wallet and vital medications. Next, you'll need some in-flight entertainment to help pass the time. A juicy novel and a phone filled with your favourite shows are some wonderful options. If you hope to take a quick snooze, a quality neck pillow and a pair of earplugs will also come in handy. Finally, make room for a toothbrush and some deodorant so you'll step off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp or pointed objects hiding in your hand luggage. Other banned items include flammable or explosive substances, like aerosols and matches, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Layer your clothing and go for shoes that are flat, enclosed and easy to take on and off.
  • 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 gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Washington?
Being prepared before your flight will help make your trip to Washington quick and painless. We've compiled some top tips for a stress-free journey through security:

  • Security personnel first need to see that you have a valid passport and matching travel documents before anything else. Have them in your hand, ready for inspection.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other small items, like coins, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
  • For just a few minutes, you'll need to unplug from the digital world. Your phone, laptop and any other electronics will also need to go through the scanner.
  • Travelling with your favourite cologne? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're permitted to bring it with you on board.
  • The right choice of footwear can save you several valuable minutes. Hiking boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed on board and will be confiscated.
