How to survive the flight to Casco?
Wherever you’re coming from, flying can be a pleasurable experience if you’re well prepared. Follow these handy tips and tricks that will help get your Casco holiday started on the right foot.What to pack in your hand luggage:

  • Air travel can be a stress-free experience if you take the right gear. Firstly, you’ll need toiletry items, such as a toothbrush and hairbrush, a spare set of clothes and a good novel. Secondly, leave space in your carry-on bag for your electronic gadgets, chargers, any daily medications and maybe a cosy neck pillow too. Last, but definitely not least, be sure to take your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes screwdrivers, drills, fuel and fireworks. Sporting equipment like golf clubs, and objects that could injure passengers, such as swords and batons, won’t be allowed on board either.

What to wear on a flight:

  • Comfort should be your highest priority when selecting what to wear on board. Consider your footwear choice carefully too, as swollen ankles and feet can be a side effect of flying. Flat, slightly roomy shoes are always a smart option.
  • The result of sustained periods of inactivity, DVT (deep vein thrombosis) is a condition that can affect some passengers on long-distance flights. But the good news is there are proven ways to reduce your risk of developing it. Keep your fluids up, walk up and down the aisles as often as possible and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to Casco?
It’s easy — be prepared. We’ve put together some handy tips and tricks for a fuss-free trip through airport security. Look out Casco, here you come:

  • Security personnel first need to establish that you have a valid ID and matching travel documents before you’re allowed to proceed any further. Keep them close by.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They’ll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your tablet and phone, must also be scanned.
  • Want to bring along your favourite hand cream? As long as the volume is no larger 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.
  • Choosing your footwear wisely can save you several minutes. Boots and bulky shoes are often required to be removed and separately scanned. Lightweight sneakers usually aren’t.
  • Airlines won’t allow any sharp or pointed objects in your carry-on luggage. If you must bring these kinds of items, put them in your checked baggage.
