Do you have any tips for my flight to Round Lake?
We've pulled together all the info you need to make your flight as pain-free as possible. Follow our insider tips and you'll be speeding through the airport and having a blast in Round Lake before you know it. What to pack in your hand luggage:

  • First, pack your passport, official ID, cash and daily medications. Next, you'll need some entertainment to help pass the time. A thrilling novel and a phone filled with your favourite shows are some wonderful options. If you intend to catch a few z's, a neck pillow and a pair of earplugs will also be useful. Finally, leave some space for a toothbrush and some deodorant so you'll arrive looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and conditioner in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as aerosols and poisons, are also restricted.

What to wear on a flight:

  • Your goal here is to feel as comfortable as possible. Go for easy-to-remove footwear, dress in loose, breathable clothing and remember to take a jacket in case you get chilly in the cabin.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To reduce your risk on board, drink plenty of water, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Round Lake?
Being organized before your flight will make your getaway to Round Lake easy and painless. Below you'll find some handy hints for a speedy journey through security:

  • Security personnel first need to determine that you have a valid passport and matching travel documents before you're allowed to proceed any further. Keep them close by.
  • Time to strip down. Well kind of. Your belt, coat, keys and other items in your pocket, like coins, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • Your electronic devices like phones and laptops will also have to go on a tray to be scanned. No need to worry though, you'll be back online soon enough.
  • Remember to remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Airlines will not allow any sharp objects to come on board with you. If you must bring these kinds of items, put them in your checked baggage.
