Do you have any tips for my flight to Troisdorf?
Depending on where you're coming from, your journey to Troisdorf could be no sweat at all or it could go on forever. We've put together some handy tips that will help you start your next great adventure on the right foot. What to pack in your hand luggage:

  • A plane ride can be a great experience if you've got all the right stuff. First of all you'll need basic toiletry items, such as a toothbrush and hairbrush, a clean set of clothes and a magazine or two. Next, find room in your hand luggage for your mobile phone, a charger, any medications and perhaps a proper neck pillow as well. Last, but definitely not least, don't forget to take your passport, travel docs and your bank cards.

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 nothing flammable, sharp or explosive. This includes knives, scissors, aerosol cans and bleaching agents. Sporting equipment like hockey sticks, and objects that could harm other people, such as firearms and ammunition, won't be allowed on board either.

What to wear on a flight:

  • Your main priority is to feel as comfortable as possible. Opt for easy-to-remove footwear, dress in loose, natural fibers and remember to bring a pullover in case it gets chilly in the cabin.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clotting due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Troisdorf?
It's all about being organised. We've compiled some handy tips and tricks for a speedy trip through security. Watch out Troisdorf, here you come:

  • Keep your travel documents and ID handy. They're the first things you'll be asked to present to security.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All electronic devices, including your phone and tablet, must also be scanned.
  • Any liquids or gels, such as perfume or hairspray, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Boots and other heavy shoes are often subjected to additional screening.
  • 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 in the cabin.
