Do you have any tips for my flight to Diest?
Depending on where you're coming from, your flight to Diest could be a breeze or it could drag on forever. We've compiled some useful travel tips that will help you start your next big adventure on a positive note. What to pack in your hand luggage:

  • First of all, pack in your passport, travel docs, cash and vital medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling novel and a phone crammed with your favourite movies are some terrific options. If you hope to take a short snooze, a quality neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, leave some space for a toothbrush and some cleansing wipes to ensure you arrive feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes knives, scissors, fireworks and fuel. Sporting equipment like ice skates, and items that could injure passengers, such as pepper spray and firearms, can't come on board with you either.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for changes in cabin temperature by layering up, and wear flat, closed-toe shoes like slip-ons.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lessen your risk on board, stay hydrated, consider wearing compression tights or socks and keep your feet and legs moving.

How to get through airport security fast when flying to Diest?
The secret is to be prepared before you reach security. That way, you'll be stepping onto that plane to Diest in no time flat. Follow these helpful tips and get your trip off to a flying start:

  • Your passport and boarding pass will need to be inspected by security personnel. Keep them handy to avoid fumbling around for them.
  • Your jacket, belt, keys and other small items, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them before your turn arrives.
  • Electronic devices like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online soon enough.
  • Travelling with your favourite cologne or perfume? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're permitted to bring it with you on board.
  • There's a chance you'll be required to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a clever idea.
  • Pocket knives and other sharp items are not allowed on board. They'll be confiscated at security, so put them in your checked suitcase.
