Do you have any tips for my flight to Kelso?
If you're not prepared, travelling can be overwhelming. But there's no need to hit the panic button just yet. Follow these useful tips for a trouble-free start to your getaway in Kelso. What to pack in your hand luggage:

  • The trick to having a pain-free travel experience is to be prepared. First up, the essentials: passport, boarding pass, cash and daily medications. Next, take on board items that'll help keep you busy, like your laptop or a thrilling book. You'll also want to bring your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Finally, be sure to pop in toiletries like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and conditioner in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your trusty Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, chemicals agents and strong acids, are also not allowed.

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in cabin temperature by layering up, and wear flat, slightly roomy shoes like slip-ons.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Kelso?
It's all about being organised. We've put together some useful tips for a stress-free trip through airport security. Watch out Kelso, here you come:

  • First things first. Your travel documents and passport will need to be presented to security personnel. Keep them within easy reach so you don't hold up the queue.
  • Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings like your belt, jacket and earphones need to go through the machine.
  • For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic gadgets will need to be sent through the scanner.
  • Can't travel without your favourite hand and nail cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on baggage.
  • Slip-on shoes are a practical footwear choice as you're less likely to be asked to remove them when passing through security. Hiking boots and other bulky shoes are often subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed on board.
