Do you have any tips for my flight to London?
If you're poorly prepared, air travel can be a real challenge. But don't hit the panic button just yet. Follow these handy tips and enjoy a hassle-free start to your vacation in London. What to pack in your hand luggage:

  • It's easy --- first, put in your passport, travel documents, bank cards and medications. Next, you'll need some extra in-flight entertainment to while away the time. A thrilling book and a tablet filled with your favourite shows are some terrific options. If you plan to take a short snooze, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some deodorant to ensure you touchdown feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes screwdrivers, drills, aerosol cans and flares. Sports equipment like hockey sticks, and items that could injure passengers, such as swords and batons, aren't allowed in the cabin either.

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for changes in temperature by dressing in layers, and pick flat, enclosed footwear like sneakers.
  • Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to London?
It's all about being prepared. We've put together some handy tips and tricks for a fuss-free trip through airport security. Watch out London, here you come:

  • Security personnel first need to check that you have a valid passport and travel documents before you're allowed to proceed any further. Have them ready to show.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off 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 need to unplug from the digital world. Your tablet, phone and any other electronic gadgets must also go through the scanner.
  • Any liquids or gels, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a good footwear choice as you're less likely to have to remove them when passing through security. Safety boots and other heavy shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed on board and will be confiscated.
