How to survive the flight to Dahlem?
Depending on where you're coming from, your trip to Dahlem could be simple and straightforward or it could drag on forever. We've compiled some useful travel tips that will help you start your next unforgettable escape on a positive note.What to pack in your hand luggage:

  • The secret to having a hassle-free flight experience is to pack ahead. Start with the essentials: passport, travel docs, credit cards and any vital medications. Next, take on board items that'll help pass the time, like your laptop or a few magazines. It's also a wise idea to pack your chargers, a comfy neck pillow and a pair of earplugs. Finally, don't forget to squeeze in toiletries like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes knives, scissors, aerosol cans and flares. Sports equipment like golf clubs, and items that could harm passengers, such as guns and swords, can't come on board with you either.

What to wear on a flight:

  • Your aim here is to feel as comfortable as possible. Dress in loose, natural fibers and pack a jacket just in case you get chilly. Always opt for flat, well-fitting shoes as your feet may swell a little during the flight. Leave the stilettos and chunky boots in your checked baggage.
  • The result of sustained periods of inactivity, DVT (deep vein thrombosis) is a blood clotting condition that can affect some passengers on long-distance flights. But the good news is there are ways to reduce your risk of developing it. Keep your fluids up, walk around the cabin wherever possible and wear compression tights or socks.

How to get through airport security fast when flying to Dahlem?
As seasoned travellers know, the secret is to be well organised before you reach airport security. That way, you'll be stepping onto that plane to Dahlem in a flash. Follow these tips and get your holiday off to a fantastic start:

  • Security personnel first need to verify that you have a valid passport and boarding pass before anything else. Have them within easy reach, ready for inspection.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • Your electronic devices like phones and laptops will also need to go on a tray for inspection. Don't worry, you'll be back online before you know it.
  • Don't forget to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a clever footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and heavier-style shoes are usually subjected to additional screening.
  • Airlines won't allow any sharp objects to come on board with you. If you need to bring these kinds of items, pack them safely in your checked luggage.
