How to survive the flight to Swansea?
No matter where you're coming from, flying can be a pleasurable experience if you prepare well enough. We've put together a list of top travel tips that will help get your Swansea escape started on the right note.What to pack in your hand luggage:

  • The secret to having a great flight experience is to pack ahead. So, let's start with the basics: passport, official ID, cash and medications. Next, bring on board items that'll help pass the time, like some electronic gadgets or a juicy novel. It's also a wise idea to pack your chargers, a neck pillow and a pair of earplugs. And of course, be sure to toss in toiletry items like a toothbrush, deodorant and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects hiding in one of the compartments of your carry-on luggage. Other banned items include explosive or flammable substances, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your number one priority is to feel as comfortable as you can. Layer up in natural-fibre clothing and remember to pack a cardigan in case it gets cool in the cabin. Pick flat, slightly roomy shoes as it's possible that your feet and ankles will swell during the flight. Leave the high heels and chunky boots in your checked luggage.
  • Unfortunately, one risk of long-distance flying is developing DVT (deep vein thrombosis), a blood clotting condition caused by extended periods of inactivity. To avoid this, take every opportunity to wander around the cabin. Compression socks and tights are another easy way to help minimize this risk.

How to get through airport security fast when flying to Swansea?
The trick is to be organised before you reach the security gate. That way, you'll be hopping onto that plane to Swansea in no time at all. Follow these helpful tips and get your holiday off to a terrific start:

  • Your boarding pass and passport will need to be presented to airport security personnel. Have them close by so you don't have to dig around for them.
  • Time to strip down. Well kind of. Your jacket, belt, keys and other small items, like your earphones, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic gadgets also need to go through the scanner.
  • Any gels or liquids, such as perfume or hairspray, that you want to bring on board must be no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • There's a possibility that you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a smart idea.
  • Airlines will not allow any pocket knives or other sharp items in your carry-on luggage. If you need to bring these kinds of items, pack them in your checked baggage.
