Do you have any tips for my flight to Sumner?
If you're not prepared, air travel can be testing. But there's no need to worry. Follow these useful tips for a pain-free start to your holiday in Sumner. What to pack in your hand luggage:

  • A plane ride can be a stress-free experience if you bring the right things. Firstly, you'll want a few toiletry items, such as toothpaste, a toothbrush and some deodorant, a spare change of clothes and a good book. Secondly, find a spot in your carry-on bag for your electronic gadgets, chargers, any medications and perhaps a quality neck pillow as well. Last, but definitely not least, remember to bring your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a Swiss Army knife lurking in one of the compartments of your hand luggage. Other restricted items include flammable or explosive products, such as bleach and fuel, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your main priority is to be as comfortable as possible. Opt for shoes that are easy to slip on and off, dress in loose, breathable clothing and don't forget to bring a jacket in case you get cold in the cabin.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long flights. Lower your risks by drinking water, keeping your ankles and legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to Sumner?
Being organised before your flight will help make your getaway to Sumner a pleasure. Below you'll find some useful tips for a stress-free journey past security:

  • Airport security personnel first need to see that you have a valid passport and matching boarding pass before anything else. Have them close by, ready for inspection.
  • Your belt, jacket, keys and other small items, like coins, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • For just a few minutes, you'll have to unplug from the digital world. Your tablet, phone and any other electronic devices also need to be sent through the scanner.
  • Remove all gels and liquids from your carry-on bag. They often need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • There's a chance you'll be asked to remove your shoes for scanning, so wearing lightweight sneakers is always a good idea.
  • Airlines won't allow any sharp objects in your hand luggage. If you must bring these kinds of items, pack them safely in your checked luggage.
