How to survive the flight to London?
If you’re poorly prepared, air travel can be a real challenge. But there’s no need to panic. Follow these helpful hints for a worry-free start to your time in London.What to pack in your hand luggage:

  • First of all, put in your passport, travel docs, cash and daily medications. Next, you’ll need some extra in-flight entertainment to while away the hours. A juicy book and a phone crammed with your favourite movies are some fantastic options. If you intend to catch a few z’s, a neck pillow and some earplugs will also be useful. Finally, squeeze in a toothbrush and some facial wipes so you’ll step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between air carriers, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes things like tools, metal cutlery, aerosol cans and bleaching agents. Sporting equipment like golf clubs, and objects that could injure passengers, such as guns and swords, aren’t allowed in the cabin either.

What to wear on a flight:

  • The key to a comfortable flight can be as simple as your clothing choices. Prepare for temperature changes by bringing layers. This will keep you nice and warm if the cabin begins to cool down. Shoes like high heels and sandals are best left for other occasions. Instead, opt for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. There’s plenty you can do to lessen your risk. Don a pair of compression socks or tights, drink lots of water often and move your legs and feet. Walk around the cabin when possible or perform some simple exercises in your seat.

How to get through airport security fast when flying to London?
A little pre-planning before your flight will make your trip to London quick and painless. Below are some handy tips for a speedy journey through security:

  • Keep your boarding pass and ID within close reach. They’ll be the first things you’ll be asked to show at airport security.
  • After that, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Personal belongings such as your belt, jacket and headphones need to go through the machine.
  • For just a few minutes, you’ll have to unplug from technology. Your tablet, phone and any other electronic devices will also need to go through the scanner.
  • Remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several precious minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren’t.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won’t be allowed on board.
