Do you have any tips for my flight to Key Largo?
We've pulled together all the info you need to make your flight as stress-free as possible. Follow our tips and tricks and you'll be speeding through airport security and exploring Key Largo in next to no time. What to pack in your hand luggage:

  • The secret to having a great flight experience is to pack in advance. So, let's start with the basics: passport, travel docs, bank cards and important medications. Next, take on board items that'll help keep you busy, like your laptop or a thrilling book. It's also smart to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to pop in toiletry items 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 hairspray in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your trusty Swiss Army knife, and dangerous products which are flammable or explosive, such as spray paint, flares and poisons, are also banned.

What to wear on a flight:

  • Your priority is to be as comfortable as you can. Pick slip-on footwear, dress in loose, natural fibers and remember to bring a pullover in case it gets chilly in the cabin.
  • Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clotting due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Key Largo?
Being organised before your flight can make your getaway to Key Largo quick and painless. We've rounded up some handy hints for a swift journey through security:

  • First things first. Your travel documents and ID will need to be inspected by airport security. Keep them within easy reach so you don't have to dig around for them.
  • Next up, both you and your hand luggage will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Personal belongings such as your belt, jacket and headphones need to go through the machine.
  • All your electronic gadgets, including your phone and tablet, will also need to be scanned.
  • Any gels or liquids, such as shampoo or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and heavier-style shoes are often subjected to additional screening.
  • Airlines will not allow any sharp or pointed objects in your carry-on baggage. If you need to bring these kinds of items, pack them safely in your checked luggage.
