Do you have any tips for my flight to Sumner?
We've rounded up all the info you need to make your flight a stress-free experience. Follow our top tips and you'll be zooming through airport security and seeing the best of Sumner in next to no time. What to pack in your hand luggage:

  • A plane ride can be a stress-free experience if you pack the right things. First things first, you'll need toiletry items, such as a toothbrush and some deodorant, a fresh change of clothes and a magazine or two. Next, find a spot in your hand luggage for your mobile phone, a charger, your medications and maybe a neck pillow as well. Lastly, remember to take your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a knife or scissors) hiding in one of the zippers of your hand luggage. Other prohibited items include flammable or explosive substances, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your priority is to feel as comfortable as possible. Opt for a pair of flat, closed-toe shoes, dress in loose, natural-fibre clothing and remember to bring a jacket in case it gets cold in the cabin.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-distance flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression tights or socks.

How to get through airport security fast when flying to Sumner?
The answer is simple --- be prepared. We've rounded up some helpful hints for a speedy trip through airport security. Watch out Sumner, here you come:

  • Be sure to have your ID and travel documents within easy reach. They're the first items you'll be asked to show at security.
  • After that, both you and your hand luggage will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Items like your coat, belt and earphones need to go through the machine.
  • Electronic devices like phones and laptops will also need to go on a tray to be scanned. Don't worry though, you'll be back online before you know it.
  • Want to bring along your favourite cologne or perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can keep it with you in your carry-on luggage.
  • Slip-on shoes are a great footwear choice as you're less likely to be required to remove them when passing through security. Boots and other heavy-style shoes are often subjected to additional screening.
  • Airlines won't allow any pocket knives or other sharp items to come on board with you. If you need to bring these kinds of items, check them in.
