How to survive the flight to Firth?
Wherever you're jetting in from, flying can be a pleasant experience if you've prepared well. Take a peek at these handy tips that will get your Firth escape started on the right foot.What to pack in your hand luggage:

  • Firstly, and most importantly, pack your passport, travel docs, cash and vital medications. Next, you'll need some in-flight entertainment to while away the hours. A juicy novel and a phone crammed with your favourite shows are some great options. If you intend to catch up on some sleep, a quality neck pillow and a pair of earplugs will also be useful. Finally, make room for a toothbrush and some cleansing wipes so you'll step off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a sharp object lurking in one of the compartments of your carry-on luggage. Other banned items include flammable or explosive substances, such as fuel and matches, and gels and liquids in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your number one priority is to be as comfortable as you can. Layer up with loose, natural-fibre clothing and pack a sweater in case it gets chilly in the cabin. Always go with well-fitting, flat shoes as your feet may swell during the journey. Leave the stilettos and heavy boots in your checked baggage.
  • Unfortunately, a risk of long-distance flying is developing DVT (deep vein thrombosis), a blood clot condition caused by prolonged periods of inactivity. To avoid this, make the most of every opportunity to stretch your legs and walk around the cabin. Compression socks and tights are another easy way to help lower your risk.

How to get through airport security fast when flying to Firth?
It's all about being prepared. We've pulled together some helpful hints for an easy trip through airport security. Watch out Firth, here you come:

  • Security personnel first need to check that you have a valid ID and boarding pass before you can proceed any further. Have them in your hand, ready for inspection.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • Your electronic devices like phones and laptops will also have to go through the machine for inspection. Don't worry though, you'll be back online before you know it.
  • Any gels or liquids, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other bulky shoes are usually subjected to extra screening.
  • Airlines won't allow any pocket knives or other sharp items in the cabin. If you must bring these kinds of items, pack them in your checked luggage.
