Do you have any tips for my flight to Siegen?
Wherever you're jetting in from, flying can be a pleasurable experience if you're well prepared. Check out these handy hints that will get your Siegen holiday started on the right note. What to pack in your hand luggage:

  • A plane ride can be a stress-free experience if you take the right things. First of all you'll need basic toiletries, such as a toothbrush and lip balm, a clean set of clothes and a good read. Secondly, make room in your carry-on bag for your mobile phone, a charger, any medications and perhaps a quality neck pillow too. Lastly, and most importantly, be sure to bring your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes things like screwdrivers, pocket knives, aerosol cans and flares. Sports equipment like ice skates, and objects that could harm other people, such as pepper spray and firearms, can't come on board with you either.

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes in the cabin by layering up, and opt for flat, slightly roomy footwear like slip-ons.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Siegen?
A little pre-planning before you arrive at the airport will make your getaway to Siegen a piece of cake. We've compiled some top tips for a speedy journey through security:

  • Be sure to have your passport and boarding pass someplace easily accessible. They're the first items you'll be asked for by security.
  • After that, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Items like your belt, coat and headphones need to go through the machine.
  • Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online in no time.
  • Any gels or liquids, such as perfume or toothpaste, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won't be allowed on board and will be confiscated.
