Do you have any tips for my flight to Herndon?
We've pulled together all the info you need to make your journey a pleasant experience. Follow our top tips and you'll be hightailing it through the airport and having a ball in Herndon in no time at all. What to pack in your hand luggage:

  • It's easy --- first, pack your passport, travel documents, credit cards and medications. Next, you'll want some entertainment to while away the time. A thrilling book and a laptop crammed with your favourite shows are some terrific options. If you intend to catch a few z's, a neck pillow and some noise-cancelling headphones will also come in handy. Finally, find room for a few toiletry items so you'll arrive feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a Swiss Army knife hiding in your hand luggage. Other prohibited items include flammable or explosive goods, such as fuel and fireworks, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes by wearing layers, and pick easy-to-remove footwear like slip-ons.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Herndon?
Being organized before your flight will help make your getaway to Herndon a pleasure. We've compiled some useful tips for a swift journey past security:

  • Airport security personnel first need to see that you have a valid passport and matching boarding pass before you can proceed any further. Have them ready for inspection.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other items in your pocket, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronic devices also need to be sent through the scanner.
  • Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • There's a good chance you'll need to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a good idea.
  • Pocket knives and other sharp items are not allowed on board. They'll be seized at security, so pack them safely away in your checked baggage.
