Firstly, you'll need basic toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh change of clothes and a good read. Next, find a spot in your carry-on bag for your laptop, a charger, your important medications and perhaps a quality neck pillow too. Lastly, remember to bring your passport, travel papers and your bank cards. > > > Do not pack the following items in your hand luggage: > > > - Double-check that you don't have sharp objects (like a pocket knife) lurking in the bottom of your hand luggage. Other banned items include flammable or explosive substances, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Comfort should be your top priority when deciding what to wear on your flight. Loose, breathable clothing is a sensible option, as are flat, closed-toe shoes. > - Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-haul flights. Lower your risks by staying hydrated, keeping your lower limbs moving and wearing compression socks or tights. ### How to get through airport security fast when flying to Prosser? > - Be sure to keep your passport and travel documents easily accessible. They're the first things you'll be asked to show at security. > - The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening. > - Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. Don't worry though, you'll be back online in no time. > - Don't forget to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag. > - There's a good chance you'll be asked to take your shoes off for scanning, so wearing lightweight sneakers is always a clever idea. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed in the cabin. ## Book with confidence # Expedia flights to Prosser Searching for cheap flights to Prosser?
