How to survive the flight to Isan-gol?
Depending on where you're coming from, your flight to Isan-gol could be a piece of cake or it could go on forever. We've rounded up some handy travel tips that will help you start your next great escape on a positive note.What to pack in your hand luggage:
  • Flying can be a great experience if you've got all the right stuff. Firstly, you'll want a few toiletry items, such as lip balm and hand cream, a spare pair of socks and something to read. Secondly, find a spot in your hand luggage for your laptop, a charger, your important medications and perhaps a quality neck pillow as well. Last, but definitely not least, remember to bring your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:
  • While the list of prohibited items can differ between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes screwdrivers, blades, fireworks and fuel. Sporting equipment like golf clubs, and objects that could harm other people, such as pepper spray and firearms, aren't allowed in the cabin either.

What to wear on a flight:
  • The key to a comfortable flight often lies in your choice of clothing. Prepare for changes in temperature by layering up. This will keep you nice and warm if the cabin starts to cool down. Shoes like stilettos, flip flops and lace-up boots are best left in your checked suitcase. Even though they may be your favourites, go for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • A condition by the name of DVT (deep vein thrombosis) is a potential risk on long-haul flights. It's the result of blood clots forming due to inactivity and poor circulation. Doing regular foot and leg exercises in your seat helps to prevent this developing. Wearing a good pair of compression tights or socks also helps reduce your risk.

How to get through airport security fast when flying to Isan-gol?
As savvy travellers know, the secret is to be well organised before you get to airport security. That way, you'll be stepping onto that plane to Isan-gol in next to no time. Follow these helpful tips and get your holiday off to a flying start:
  • Your travel documents and passport will need to be presented to airport security personnel. Have them easily accessible so you don't have to dig around for them.
  • The X-ray machine is up next. Remove anything on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like phones and laptops will also have to go through the machine for inspection. Don't worry though, you'll be back online soon enough.
  • Want to bring along your favourite perfume or cologne? As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you're allowed to bring it with you on board.
  • The right choice of footwear can save you several minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Sharp items are not allowed in the cabin. They'll be seized at security, so pack them safely away in your checked luggage.
