Do you have any tips for my flight to Caernarfon?
Depending on where you're coming from, your flight to Caernarfon could be completely painless or it could go on forever. We've rounded up some useful hints that will help you start your next big adventure on a positive note. What to pack in your hand luggage:
  • The secret to having a great flight experience is to be prepared. Start with the essentials: passport, travel docs, credit cards and vital medications. Next, bring items that'll help keep you entertained, like your laptop or a good read. It's also wise to bring your chargers, a comfy neck pillow and a pair of headphones. Finally, don't forget to pop in toiletries like a toothbrush, deodorant and a fresh change of clothes.
Do not pack the following items in your hand luggage:
  • While the list of restricted items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes things like knives, scissors, aerosol cans and flares. Sports equipment like hockey sticks, and objects that could harm other people, such as pepper spray and firearms, are also banned from the cabin.
What to wear on a flight:
  • The aisles of an aircraft are no place for a fashion parade. Layer your clothing and opt for shoes that are closed-toe, flat and easy to take on and off.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to poor circulation, 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 Caernarfon?
Being prepared before your flight will help make your trip to Caernarfon easy and painless. Check out our top tips for a stress-free journey past security:
  • Security personnel first need to make sure that you have a valid ID and travel documents before you're allowed to proceed any further. Have them ready for inspection.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to beep. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All your electronic devices, including your phone and tablet, will also need to be scanned separately.
  • Don't forget to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • It's also likely that you'll be required to take your shoes off for scanning, so wearing slip-on shoes is always a clever idea.
  • Sharp items such as knives and scissors can't be taken on board. They'll be seized at security, so put them in your checked suitcase.
