How to survive the flight to London?
Wherever you’re jetting in from, flying can be a pleasant experience if you prepare well enough. We’ve put together a list of handy tips and tricks that will help get your London escape started on the right foot.What to pack in your hand luggage:

  • Air travel can be a stress-free experience if you pack the right gear. Firstly, you’ll want some basic toiletries, such as deodorant and a toothbrush, a clean pair of socks and a good book. Next, leave space in your carry-on bag for your electronic devices, chargers, any medications and perhaps a quality neck pillow as well. Lastly, and most importantly, don’t forget to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Sharp objects, like your treasured pocket knife, and dangerous products which are explosive or flammable, such as aerosol cans, flares and strong acids, are also not allowed.

What to wear on a flight:

  • Comfort should be your priority when selecting what to wear on board. Consider your footwear choice carefully too, as swollen feet are a common side effect of flying. Shoes which are flat and slightly roomy work well.
  • The result of sustained periods of immobility, DVT (deep vein thrombosis) is a blood clotting condition that can affect some passengers on long-distance flights. But the great news is there are proven ways to reduce the risk of developing it. Stay well hydrated, wander around the cabin as often as you can and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to London?
The secret is to be well prepared before you arrive at the security gate. That way, you’ll be boarding that plane to London in the blink of an eye. Follow these helpful tips and get your holiday off to a terrific start:

  • Your travel ID and boarding pass will need to be shown to security personnel. Keep them handy so you don’t have to dig around for them.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. This includes things like earphones or headphones, as well as heavy coats or jackets. They’ll all need to go on the X-ray conveyor belt.
  • Electronic devices like phones and laptops will also need to go on a tray to be scanned. No need to worry though, you’ll be back online soon enough.
  • Remove all liquids and gels from your hand luggage. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you a few precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren’t.
  • Pocket knives and other sharp items can’t be taken on board. They’ll be seized at security, so pack them in your checked bags.
