Next, you'll want some extra in-flight entertainment to while away the hours. A thrilling book and a phone crammed with your favourite shows are some fantastic options. If you intend to take a quick nap, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, squeeze in a toothbrush and some deodorant so you'll arrive feeling fresh as a daisy. > > > Do not pack the following items in your hand luggage: > > > - While the list of restricted items differs between airlines, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like box cutters, razor blades, fuel and fireworks. Sports equipment like baseball bats, and items that could harm other people, such as pepper spray and guns, can't come on board with you either. > > > What to wear on a flight: > > > - Comfort should be your main priority when deciding what to wear on your flight. Loose clothing is a wise choice, as are flat, slightly roomy shoes. > - Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Treffen? > - Security personnel first need to make sure that you have a valid ID and matching travel documents before anything else. Keep them close by. > - The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt. > - All electronic devices, including your phone and tablet, will also need to be scanned separately. > - Remember to remove liquids and gels from your hand luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag. > - Choosing your footwear wisely can save you valuable minutes. Boots and bulky shoes are often required to be removed and separately scanned. Lightweight sneakers are usually not. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed in the cabin. __Flights to Treffen information__ | Destination airport | Woerthersee | | ----------------------------- | ----------- | | Destination airport IATA code | KLU | | Destination city name | Klagenfurt | | Return price | £40 | ## Trending flights to Treffen Prices were available within the past 7 days and start at £20 for one-way flights and £40 for round trip, for the period specified.
