Do you have any tips for my flight to London?
If you're poorly prepared, airports and flying can be testing. But there's no need to hit the panic button just yet. Follow these handy hints for a stress-free start to your getaway in London. What to pack in your hand luggage:

  • The trick to having a worry-free flight experience is to pack ahead. Start with the essentials: passport, travel docs, credit cards and medications. Next, bring items that'll help keep you occupied, like some electronic gadgets or a good book. You'll also want to pack your chargers, a quality neck pillow and a pair of headphones. And of course, don't forget to squeeze in toiletries like a toothbrush, lip balm and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule of thumb is nothing sharp, flammable or explosive. This includes screwdrivers, pocket knives, aerosol cans and bleaching agents. Sporting equipment like baseball bats, and items that could harm other people, such as swords and guns, are also banned from the cabin.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for changes in temperature by dressing in layers, and opt for flat, easy-to-remove shoes like slip-ons.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to London?
Being prepared before you get to the airport can make your trip to London quick and painless. Below you'll find some handy hints for a speedy journey through security:

  • First things first. Your travel ID and boarding pass will need to be presented to security personnel. Have them easily accessible to avoid fumbling around for them.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • For just a few minutes, you'll have to unplug from the digital world. Your laptop, phone and any other electronic devices will also need to be sent through the scanner.
  • Travelling with a new hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're allowed to bring it with you in your carry-on bag.
  • There's a possibility that you'll be required to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a wise idea.
  • Airlines will not allow any sharp objects in the cabin. If you must bring these kinds of items, put them in your checked baggage.
