Do you have any tips for my flight to Isleworth?
If you're poorly prepared, air travel can be a real challenge. But there's no need to hit the panic button just yet. Follow these useful tips and enjoy a worry-free start to your getaway in Isleworth. What to pack in your hand luggage:

  • First things first, put in your passport, important documents, bank cards and medications. Next, you'll need some in-flight entertainment to help pass the time. A juicy book and a phone crammed with your favourite shows are some fantastic options. If you plan to take a short nap, a quality neck pillow and some noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes so you'll hop off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like your treasured Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosols and poisons, are also restricted.

What to wear on a flight:

  • Your top priority is to feel as comfortable as possible. Pick a pair of slip-on shoes, dress in loose, natural fibers and remember to take a sweater in case it gets chilly in the cabin.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Lower your risks by staying hydrated, keeping your ankles and legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to Isleworth?
As seasoned travellers know, the secret is to be well organised before you reach airport security. That way, you'll be hopping onto that plane to Isleworth in next to no time. Follow these tips and get your trip off to a fantastic start:

  • First things first. Your travel documents and passport will need to be shown to airport security. Keep them someplace accessible so you don't have to dig around for them.
  • Your jacket, belt, keys and other items in your pocket, like your headphones, will be required to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • For just a few moments, you'll have to unplug from the digital world. Your phone, laptop and any other electronics will also need to go through the scanner.
  • Remember to remove gels and liquids from your carry-on 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 in a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a clever footwear choice as you're less likely to have to remove them when passing through security. Safety boots and other bulky shoes are often subjected to extra screening.
  • Sharp or pointed items are not allowed on board. They'll be seized at security, so pack them safely away in your checked suitcase.
