Do you have any tips for my flight to Index?
Depending on where you're coming from, your trip to Index could be no sweat at all or it could go on forever. We've pulled together some useful hints that will help you start your next great escape on a positive note. What to pack in your hand luggage:
  • The trick to having a pain-free travel experience is to plan ahead. So, let's start with the basics: passport, travel documents, cash and medications. Next, bring on board items that'll help pass the time, like some electronic devices or a good book. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to toss in toiletries like a toothbrush, lip balm and a clean T-shirt.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items differs between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes screwdrivers, blades, fuel and fireworks. Sporting equipment like ski poles, and items that could harm passengers, such as swords and guns, can't come on board with you either.
What to wear on a flight:
  • Your aim is to be as comfortable as you can. Choose shoes that are easy to pull on and off, dress in loose, breathable clothing and remember to bring a sweater in case it gets cold in the cabin.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To minimize your risk on board, drink plenty of water, consider wearing compression socks and do gentle foot and leg exercises in your seat.
How to get through airport security fast when flying to Index?
Being prepared before you get to the airport will make your trip to Index a piece of cake. Below you'll find some handy tips for a speedy journey past security:
  • First things first. Your boarding pass and travel ID will need to be inspected by airport security. Have them easily accessible so you don't hold up the queue.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronics, including your tablet and phone, are also required to be scanned separately.
  • Remember to 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 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a great footwear choice as you're less likely to have to remove them when going through security. Boots and other heavy-style shoes are usually subjected to additional screening.
  • Airlines will not allow any pocket knives or other sharp items in the cabin. If you must bring these kinds of items, pack them in your checked baggage.
