How to survive the flight to London?
Depending on where you’re coming from, your trip to London could be no sweat at all or it could go on forever. We’ve put together some handy hints that will help you start your next great adventure on a positive note.What to pack in your hand luggage:

  • The secret to having a great travel experience is to plan ahead. So, let’s start with the basics: passport, boarding pass, bank cards and vital medications. Next, bring on board items that’ll help keep you occupied, like your laptop or a juicy novel. It’s also wise to pack your chargers, a quality neck pillow and a pair of earplugs. And of course, don’t forget to toss in toiletry items like a toothbrush, cleansing wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes things like knives, scissors, fuels and bleaching agents. Sports equipment like ice skates, and objects that could injure passengers, such as pepper spray and guns, can’t come on board with you either.

What to wear on a flight:

  • Comfort should be your prime concern when choosing what to wear during your flight. Consider your choice of footwear with care too, as swollen feet and ankles are a common occurrence. Flat, slightly roomy shoes are your best bet.
  • A condition called deep vein thrombosis (DVT) can pose a risk on long-distance flights. It’s the result of blood clots forming due to poor circulation. Doing leg and foot exercises in your seat is a great way to prevent this from occurring. Wearing a high-quality pair of compression socks or tights is also a wise idea.

How to get through airport security fast when flying to London?
As seasoned travellers know, the secret is to be well prepared before you get to security. 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 spectacular start:

  • Be sure to keep your travel documents and passport within close reach. They’ll be the first things you’ll be asked to present to airport security.
  • The X-ray machine comes next. Remove anything metal on you 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.
  • All your electronic devices, including your laptop and phone, will also need to be scanned separately.
  • Any gels or liquids, such as hair oil or hand cream, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • It’s also possible you’ll be asked to take your shoes off for scanning, so wearing lightweight sneakers is always a wise idea.
  • Sharp or pointed objects (like knives and scissors) can’t be taken on board. They’ll be seized at security, so pack them in your checked suitcase.
