First up, the essentials: passport, travel docs, bank cards and important medications. Next, bring on board items that'll help while away those hours, like some electronic gadgets or a good read. You'll also want to bring your chargers, a neck pillow and a pair of headphones. Finally, don't forget to pop in toiletries like a toothbrush, cleansing wipes and a spare set of clothes. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items differs between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like box cutters, razor blades, aerosol cans and bleaching agents. Sporting equipment like bows and arrows, and objects that could harm passengers, such as firearms and swords, can't come on board with you either. > > > What to wear on a flight: > > > - Go for comfort over style. Prepare for changes in temperature by wearing layers, and pick slightly roomy, flat shoes like sneakers. > - Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It's the result of blood clotting due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks. ### How to get through airport security fast when flying to Interior? > - Keep your passport and travel documents close by. They're the first items you'll be asked to present to airport security. > - Next up, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items like your jacket, belt and headphones need to go through the machine. > - Your electronic devices like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online in no time. > - Remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag. > - There's a chance you'll be asked to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a smart idea. > - Sharp items like knives are prohibited in the cabin. They'll be confiscated at security, so put them in your checked bags. __Flights to Interior information__ | Destination airport | Rapid City Regional | | ----------------------------- | ------------------- | | Destination airport IATA code | RAP | | Destination city name | Rapid City | | Return price | £412 | ## Trending flights to Interior Prices were available within the past 7 days and start at £166 for one-way flights and £413 for round trip, for the period specified.
