Do you have any tips for my flight to Casco?
If you're poorly prepared, airports and flying can be overwhelming. But there's no need to hit the panic button just yet. Follow these handy tips and enjoy a worry-free start to your time in Casco. What to pack in your hand luggage:

  • The trick to having a worry-free flight experience is to pack in advance. So, let's start with the essentials: passport, official ID, bank cards and vital medications. Next, take on board items that'll help keep you busy, like some electronic devices or a magazine. You'll also want to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, be sure to pop in toiletries like a toothbrush, lip balm and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like screwdrivers, knives, spray paint and fireworks. Sports equipment like hockey sticks, and items that could harm other people, such as firearms and swords, can't come on board with you either.

What to wear on a flight:

  • Comfort should be your main priority when deciding what to wear on board. Loose clothing is a wise option, as are flat, slightly roomy shoes.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to Casco?
Being organized before your flight can make your getaway to Casco easy and painless. Here are some handy tips and tricks for a swift journey past security:

  • Airport security personnel first need to know that you have a valid passport and matching travel documents before you can proceed any further. Have them ready for inspection.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other items in your pocket, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • Electronic devices like phones and laptops will also have to go on a tray to be scanned. No need to worry though, you'll be back online soon enough.
  • Want to bring along your favourite cologne? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can bring it with you in your carry-on baggage.
  • There's a chance you'll be asked to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won't be allowed on board.
