Do you have any tips for my flight to Rialto?
We've pulled together all the info you need to make your journey as enjoyable as possible. Follow our tips and you'll be cruising through the airport and discovering Rialto in no time flat. What to pack in your hand luggage:

  • Flying can be a great experience if you've got all the right gear. Firstly, you'll want some basic toiletries, such as a toothbrush and some deodorant, a fresh set of clothes and a magazine or two. Next, leave space in your hand luggage for your electronic devices, chargers, any daily medications and maybe a quality neck pillow as well. Lastly, be sure to take your passport, travel docs and some money.

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 avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, pocket knives, aerosol cans and bleaching agents. Sporting equipment like hockey sticks, and items that could injure passengers, such as pepper spray and guns, won't be allowed on board either.

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on board. Loose clothing is a smart option, as are enclosed shoes like sneakers.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-haul flights. Lower your risks by staying hydrated, keeping your legs and feet moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Rialto?
The simple answer is — be prepared. We've pulled together some handy tips and tricks for a speedy trip through airport security. Watch out Rialto, here you come:

  • Airport security personnel first need to make sure that you have a valid passport and matching travel documents before you can proceed any further. Have them ready to show.
  • Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
  • For just a few minutes, you'll have to unplug from the digital world. Your phone, laptop and any other electronic devices will also need to go through the scanner.
  • Any liquids or gels, such as perfume or toothpaste, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Airlines will not allow any sharp objects in your carry-on luggage. If you need to bring these kinds of items, pack them safely in your checked luggage.
