Do you have any tips for my flight to Potomac?
If you're poorly prepared, airports and flying can be a real challenge. But there's no need to worry. Follow these handy tips and enjoy a worry-free start to your time in Potomac. What to pack in your hand luggage:

  • A plane trip can be a pleasure if you bring the right gear. Firstly, you'll need toiletry items, such as lip balm and hand cream, a clean pair of socks and a magazine or two. Next, make room in your carry-on bag for your mobile phone, a charger, your important medications and perhaps a blow-up neck pillow too. Lastly, remember to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a pocket knife) lurking in your carry-on luggage. Other banned items include flammable or explosive goods, such as aerosol cans and bleach, and liquids and gels in containers with a volume of more 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 up with comfy clothing and pick shoes that are flat, roomy and easy to pull on and off.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from 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.

How to get through airport security fast when flying to Potomac?
The trick is to be well organized before you get to the airport security gate. That way, you'll be stepping onto that plane to Potomac in a flash. Follow these tips and get your vacation off to a terrific start:

  • Be sure to have your ID and boarding pass within close reach. They're the first items you'll be asked to present to airport security.
  • Your coat, belt, keys and other items in your pocket, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process faster 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 electronic devices will need to go through the scanner.
  • Remember to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and heavier-style shoes are usually subjected to additional screening.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you must bring these kinds of items, put them in your checked baggage.
