Do you have any tips for my flight to Marathon?
Depending on where you're coming from, your journey to Marathon could be as easy as pie or it could drag on forever. We've pulled together some useful travel tips that will help you start your next big adventure on a positive note. What to pack in your hand luggage:

  • First of all, pack your passport, travel documents, cash and vital medications. Next, you'll need some in-flight entertainment to help pass the time. A juicy book and a tablet filled with your favourite shows are some wonderful options. If you plan to catch up on some sleep, a quality neck pillow and a pair of earplugs will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes so you'll touchdown feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your trusty pocket knife, and dangerous goods which are explosive or flammable, such as flares, bleaching agents and fuels, are also restricted.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for changes in cabin temperature by layering up, and wear flat, slightly roomy footwear like sneakers.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Reduce the risks by staying hydrated, keeping your legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Marathon?
As savvy travellers know, the secret is to be organized before you get to the security gate. That way, you'll be hopping onto that plane to Marathon in no time flat. Follow these tips and get your trip off to a spectacular start:

  • Be sure to keep your ID and boarding pass within close reach. They're the first items you'll be asked for by security.
  • Your belt, jacket, keys and other items in your pocket, like coins, will be required to go through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
  • Your electronic devices like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online soon enough.
  • Remove all liquids and gels from your hand luggage. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Pocket knives and other sharp items are not allowed in the cabin. They'll be seized at security, so pack them in your checked bags.
