Do you have any tips for my flight to Gaithersburg?
We've rounded up all the info you need to make your journey a pleasant experience. Follow our tips and you'll be breezing through airport security and discovering Gaithersburg before you know it. What to pack in your hand luggage:

  • Air travel can be a pleasure if you bring the right things. First of all you'll need basic toiletries, such as deodorant and a toothbrush, a fresh change of clothes and a few magazines. Next, leave space in your carry-on bag for your mobile phone, a charger, your medications and perhaps a neck pillow too. Lastly, and most importantly, don't forget to take your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like knives, scissors, fuel and fireworks. Sports equipment like bows and arrows, and items that could harm passengers, such as swords and batons, can't come on board with you either.

What to wear on a flight:

  • Comfort should be your top priority when choosing what to wear during your flight. Loose, breathable clothing is a wise option, as are flat, slip-on shoes.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Lower your risks by drinking water, keeping your legs and ankles moving and wearing compression socks or tights.

How to get through airport security fast when flying to Gaithersburg?
The answer is — be prepared. We've put together some helpful hints for a hassle-free trip through security. Look out Gaithersburg, here you come:

  • Airport security personnel first need to verify that you have a valid ID and matching travel documents before anything else. Have them close by, ready for inspection.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • Your electronic gadgets like laptops and phones will also have to go through the machine for inspection. No need to worry though, you'll be back online before you know it.
  • Can't travel without your favourite hand cream? Not a problem. As long as it's in a container 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.
  • Slip-on shoes are a clever footwear choice as you're less likely to be required to remove them when passing through security. Boots and heavier-style shoes are often subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed in the cabin.
