Do you have any tips for my flight to Key Biscayne?
We've pulled together all the info you need to make your flight a pleasant experience. Follow our tips and tricks and you'll be cruising through airport security and discovering Key Biscayne before you know it. What to pack in your hand luggage:

  • First of all, pack in your passport, travel documents, credit cards and daily medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling novel and a tablet crammed with your favourite movies are some terrific options. If you plan to take a quick nap, a comfy neck pillow and some earplugs will also come in handy. Finally, leave some space for a few toiletry items so you'll arrive at your destination looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a pocket knife) lurking in the bottom of your carry-on luggage. Other prohibited items include explosive or flammable products, such as fuel and fireworks, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your number one priority when deciding what to wear during your flight. Loose clothing is a smart option, as are flat, enclosed shoes.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks or tights.

How to get through airport security fast when flying to Key Biscayne?
Being prepared before your flight will make your trip to Key Biscayne a pleasure. Below are some handy tips and tricks for a speedy journey past security:

  • Security personnel first need to verify that you have a valid ID and boarding pass before you can proceed any further. Have them ready for inspection.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronic gadgets must also go through the scanner.
  • Any liquids or gels, such as perfume or toothpaste, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and other heavy-style shoes are often subjected to extra screening.
  • Airlines won't allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, pack them in your checked baggage.
