Do you have any tips for my flight to Firth?
If you're not prepared, travelling can be daunting. But there's no need to hit the panic button just yet. Follow these helpful hints for a comfortable start to your vacation in Firth. What to pack in your hand luggage:

  • Flying can be a cruisy experience if you've got all the right stuff. Firstly, you'll want a few basic toiletries, such as a toothbrush and lip balm, a spare set of clothes and a good read. Secondly, find a spot in your hand luggage for your laptop, a charger, any daily medications and perhaps a blow-up neck pillow too. Lastly, remember to take your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your trusty pocket knife, and products which are flammable or explosive, such as aerosol cans, spray paint and gasoline, are also prohibited.

What to wear on a flight:

  • Your main priority is to feel as comfortable as possible. Choose easy-to-remove footwear, dress in loose, natural-fibre clothing and don't forget to bring a pullover in case you get cold in the cabin.
  • You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lower your risk on board, drink lots of water, consider wearing compression socks and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Firth?
The answer is --- be prepared. We've pulled together some top tips for a fuss-free trip through airport security. Watch out Firth, here you come:

  • Airport security personnel first need to know that you have a valid passport and travel documents before anything else. Have them within easy reach, ready for inspection.
  • Your belt, coat, keys and other small items, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them as your turn draws near.
  • All your electronic devices, including your tablet and phone, are also required to be scanned separately.
  • Remember to remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Airlines won't allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, put them in your checked baggage.
