Do you have any tips for my flight to Koin?
No matter where you're coming from, flying can be an enjoyable experience if you're well organised. We've compiled a list of handy tips that will get your Koin holiday started on the right foot. What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, travel docs, bank cards and daily medications. Next, you'll want some entertainment to help pass the time. A thrilling novel and a tablet crammed with your favourite movies are good options. If you plan to catch a few z's, a neck pillow and a pair of earplugs will also be useful. Finally, squeeze in a toothbrush and some deodorant so you'll arrive at your destination looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, drills, spray paint and fireworks. Sports equipment like ice skates, and objects that could harm other people, such as firearms and ammunition, won't be allowed on board either.

What to wear on a flight:

  • Your main priority is to feel as comfortable as you can. Choose flat, closed-toe shoes, dress in loose, natural-fibre clothing and remember to take a sweater in case it gets chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Koin?
A little pre-planning before you get to the airport will make your trip to Koin quick and painless. Here are some useful tips and tricks for a swift journey through security:

  • Be sure to keep your ID and boarding pass handy. They're the first things you'll be asked to show at airport security.
  • After that, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that might trigger the alarms. Personal belongings like your coat, belt and headphones will be required to go through the machine.
  • For just a few minutes, you'll need to unplug from technology. Your laptop, phone and any other electronic gadgets will need to be sent through the scanner.
  • Travelling with a new hand and nail cream? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's fine to bring with you on board.
  • It's also possible you'll need to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a smart idea.
  • Sharp items are not allowed on board. They'll be confiscated at security, so put them in your checked luggage.
