Do you have any tips for my flight to Dulles?
We've got the lowdown on how to make your flight as enjoyable as possible. Follow our tips and you'll be cruising through airport security and discovering Dulles in next to no time. What to pack in your hand luggage:

  • Travelling on a plane can be easy if you pack the right stuff. First of all you'll need toiletry items, such as lip balm and hand cream, a spare pair of socks and something to read. Next, leave space in your carry-on bag for your electronic gadgets, chargers, your medications and perhaps a cozy neck pillow too. Lastly, be sure to take your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between airlines, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, drills, aerosol cans and flares. Sporting equipment like hockey sticks, and items that could injure passengers, such as firearms and swords, are also banned from the cabin.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Wear layers and choose shoes that are flat, roomy and easy to take on and off.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Dulles?
The trick is to be well prepared before you reach airport security. That way, you'll be hopping onto that plane to Dulles in the blink of an eye. Follow these helpful tips and get your vacation off to a great start:

  • Keep your boarding pass and passport easily accessible. They're the first items you'll be asked for by security.
  • Time to strip down. Well sort of. Your belt, jacket, keys and other contents of your pockets, like coins, will be required to go through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
  • For just a few moments, you'll have to unplug from technology. Your tablet, phone and any other electronics will need to be sent through the scanner.
  • Any gels or liquids, such as hair oil or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • There's a good chance you'll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a good idea.
  • Sharp or pointed items can't be taken on board. They'll be confiscated at security, so pack them in your checked luggage.
