Do you have any tips for my flight to Rialto?
Depending on where you're coming from, your trip to Rialto could be a breeze or it could go on forever. We've compiled some tips that will help you start your next great escape on the right foot. What to pack in your hand luggage:

  • First things first, pack in your passport, travel documents, credit cards and vital medications. Next, you'll want some extra in-flight entertainment to help pass the time. A thrilling novel and a phone filled with your favourite shows are some fantastic options. If you plan to catch forty winks, a neck pillow and some earplugs will also come in handy. Finally, find room for a toothbrush and some deodorant to ensure you arrive looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, bleaching agents and poisons, are also banned.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Dress in comfortable layers and pick shoes that are flat and easy to slip on and off.
  • The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-haul flights. Lower your risks by staying hydrated, keeping your ankles and legs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Rialto?
The trick is to be organised before you reach security. That way, you'll be hopping onto that plane to Rialto in next to no time. Follow these tips and get your trip off to a flying start:

  • Be sure to keep your travel documents and passport within easy reach. They're the first items you'll be asked to present to airport security.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • Electronic devices like laptops and phones will also have to go through the machine for inspection. Don't worry though, you'll be back online in no time.
  • Want to bring along your favourite cologne or perfume? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on bag.
  • The right choice of footwear can save you a few precious minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be seized at security, so pack them in your checked baggage.
