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

  • Travelling on a plane can be a cruisy experience if you carry the right gear. Firstly, you'll want a few toiletry items, such as deodorant, toothpaste and a toothbrush, a spare change of clothes and something to read. Secondly, leave space in your hand luggage for your laptop, a charger, any vital medications and perhaps a neck pillow as well. Lastly, and most importantly, remember to take your passport, travel docs and some money.

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 things like box cutters, razor blades, spray paint and fireworks. Sporting equipment like baseball bats, and objects that could injure passengers, such as pepper spray and firearms, aren't allowed in the cabin either.

What to wear on a flight:

  • Comfort should be your main priority when deciding what to wear during your flight. Loose clothing is a wise option, as are flat, slip-on shoes.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-haul flights. Reduce the risks by staying hydrated, keeping your feet and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Dahlem?
A little pre-planning before your flight will make your trip to Dahlem a breeze. Read through our handy hints for a swift journey past security:

  • Your passport and boarding pass will need to be shown to airport security personnel. Keep them at hand so you don't have to dig around for them.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronics, including your tablet and phone, will also need to be scanned separately.
  • Travelling with your favourite hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on.
  • The right choice of footwear can save you several valuable minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Pocket knives and other sharp items are not allowed in the cabin. They'll be confiscated at security, so put them in your checked baggage.
