Do you have any tips for my flight to Monmouth?
If you're not prepared, travelling can be a real challenge. But there's no need to hit the panic button just yet. Follow these tips and tricks and enjoy a pain-free start to your holiday in Monmouth. What to pack in your hand luggage:

  • The trick to having an amazing flight experience is to be prepared. So, let's start with the essentials: passport, boarding pass, credit cards and any vital medications. Next, bring items that'll help keep you entertained, like your laptop or a thrilling novel. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, be sure to squeeze in toiletry items like a toothbrush, deodorant and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your beloved Swiss Army knife, and products which are flammable or explosive, such as flares, bleaching agents and fireworks, are also not allowed.

What to wear on a flight:

  • The aisles of an aircraft aren't the place for a fashion parade. Layer up with comfy clothing and go for shoes that are enclosed, flat and easy to pull on and off.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clotting due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

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

  • Keep your passport and travel documents close by. They'll be the first things you'll be asked for by security.
  • After that, both you and your carry-on bag will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and headphones need to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go on a tray for inspection. Don't worry though, you'll be back online soon enough.
  • Any liquids or gels, such as hair oil or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • There's a good chance you'll be required to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a wise idea.
  • Sharp items like knives can't be taken on board. They'll be confiscated at security, so put them in your checked luggage.
