Do you have any tips for my flight to Rosemont?
Wherever you're coming from, flying can be a pleasant experience if you're well prepared. We've put together a list of handy hints that will help get your Rosemont escape started on the right note. What to pack in your hand luggage:

  • First, pack in your passport, official ID, bank cards and medications. Next, you'll want some in-flight entertainment to help pass the time. A juicy book and a phone crammed with your favourite shows are some terrific options. If you intend to catch forty winks, a neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, leave some space for a toothbrush and some facial wipes to ensure you touchdown looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes tools, metal cutlery, fireworks and fuel. Sporting equipment like ice skates, and objects that could harm passengers, such as firearms and swords, won't be allowed on board either.

What to wear on a flight:

  • Comfort should be your main priority when deciding what to wear during your flight. Loose, breathable clothing is a smart option, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Rosemont?
As savvy travellers know, the secret is to be organised before you get to security. That way, you'll be hopping onto that plane to Rosemont in no time at all. Follow these tips and get your holiday off to a terrific start:

  • Security personnel first need to verify that you have a valid passport and matching travel documents before you can proceed any further. Keep them within easy reach.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. 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 soon enough.
  • Remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Airlines won't allow any sharp objects to come on board with you. If you must bring these kinds of items, put them in your checked luggage.
