Do you have any tips for my flight to Trefor?
We've got the lowdown on how to make your flight a stress-free experience. Follow our tips and tricks and you'll be breezing through airport security and enjoying Trefor before you know it. What to pack in your hand luggage:

  • First of all, put in your passport, official ID, bank cards and medications. Next, you'll want some in-flight entertainment to help pass the time. A juicy novel and a tablet filled with your favourite shows are some wonderful options. If you hope to catch forty winks, a quality neck pillow and some earplugs will also be useful. Finally, leave space for a toothbrush and some cleansing wipes to ensure you step off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, flares and fireworks, are also not allowed.

What to wear on a flight:

  • Your main priority is to be as comfortable as you can. Pick a pair of flat, closed-toe shoes, dress in loose, natural fibers and don't forget to take a sweater in case it gets cold in the cabin.
  • You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lower your risk on board, drink lots of water, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to Trefor?
The answer is simple — be organised. We've compiled some tips and tricks for a hassle-free trip through airport security. Look out Trefor, here you come:

  • Security personnel first need to see that you have a valid passport and boarding pass before anything else. Have them close by, ready for inspection.
  • After that, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that might trigger the alarms. Items such as your belt, jacket and headphones will be required to go through the machine.
  • For just a few minutes, you'll need to unplug from the digital world. Your phone, laptop and any other electronics must also go through the scanner.
  • Don't forget to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • It's also possible you'll need to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a smart idea.
  • Airlines won't allow any sharp items or pocket knives in the cabin. If you must bring these kinds of items, check them in.
