How to survive the flight to Washington?
No matter where you’re coming from, flying can be a pleasurable experience if you prepare well enough. We’ve made a list of handy hints that will get your Washington holiday started on the right note.What to pack in your hand luggage:

  • Flying can be a pleasure if you pack the right things. Firstly, you’ll want a few basic toiletry items, such as lip balm and hand cream, a spare pair of socks and a good novel. Next, leave space in your carry-on bag for your phone and charger, any vital medications and maybe a proper neck pillow too. Lastly, remember to take your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Pointed or sharp objects, like your pocket knife, and dangerous products which are explosive or flammable, such as flares, chemicals agents and strong acids, are also prohibited.

What to wear on a flight:

  • Comfort should always be your main priority when deciding what to wear on your flight. Consider your footwear choice with care too, as swollen feet and ankles can be a side effect of flying. Shoes which are flat and slightly roomy are always a smart option.
  • Caused by sustained periods of immobility, DVT (deep vein thrombosis) is a blood clotting condition that can affect passengers on long-haul flights. But the great news is there are proven ways to reduce the risk of developing it. Keep your fluids up, walk up and down the aisles whenever possible and wear compression socks or tights.

How to get through airport security fast when flying to Washington?
The secret is to be prepared before you arrive at airport security. That way, you’ll be hopping onto that plane to Washington in no time at all. Follow these tips and get your holiday off to a great start:

  • First things first. Your ID and travel documents will need to be shown to airport security personnel. Keep them handy to avoid fumbling around for them.
  • The X-ray machine is up next. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as your coat or jacket. They’ll all need to go on the X-ray conveyor belt.
  • For just a few minutes, you’ll need to unplug from technology. Your laptop, phone and any other electronics must also be sent through the scanner.
  • Travelling with your favourite perfume? Not a problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it’s stored in a zip-close bag, you can bring it with you in your carry-on bag.
  • It’s also likely that you’ll need to take your shoes off for scanning, so wearing slip-on shoes is always a smart idea.
  • Avoid taking prohibited items in 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.
