How to survive the flight to Petros?
Depending on where you're coming from, your flight to Petros could be completely painless or it could drag on forever. We've rounded up some handy tips that will help you start your next great escape on the right foot.What to pack in your hand luggage:

  • The secret to having a hassle-free travel experience is to plan ahead. So, let's start with the basics: passport, boarding pass, bank cards and daily medications. Next, bring on board items that'll help keep you entertained, like your laptop or a magazine. It's also smart to pack your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to chuck in toiletry items like a toothbrush, deodorant and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a pocket knife lurking in one of the compartments of your carry-on luggage. Other banned items include explosive or flammable goods, such as aerosol cans and bleach, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The answer to a comfortable flight can be as simple as your choice of clothing. Prepare yourself for varying temperatures by layering up. That way you'll stay nice and warm if the cabin gets chilly. Shoes like high heels and sandals are best left in your suitcase. Even though they may be your favorites, opt for flat, closed-toed footwear like slip-ons. Your feet will thank you for it.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a serious condition that can affect passengers during long-haul flights. But the great news is there are numerous ways to significantly reduce the risk of developing it. Stay hydrated, wander through the cabin as much as possible and wear compression tights or socks.

How to get through airport security fast when flying to Petros?
Being organized before your flight will make your trip to Petros quick and painless. Here are some useful tips for a stress-free journey through security:

  • Be sure to keep your boarding pass and passport close by. They're the first things you'll be asked for by airport security.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online before you know it.
  • Remove liquids and gels from your hand luggage. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag.
  • The right choice of footwear can save you several precious minutes. Boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Pocket knives and other sharp items are not allowed on board. They'll be confiscated at security, so put them in your checked bags.
