Do you have any tips for my flight to Round Lake?
If you're poorly prepared, air travel can be a real challenge. But don't hit the panic button just yet. Follow these tips and tricks for a stress-free start to your time in Round Lake. What to pack in your hand luggage:
  • Flying can be easy if you take the right stuff. Firstly, you'll want some basic toiletry items, such as lip balm and hand cream, a clean pair of socks and a good book. Secondly, leave space in your carry-on bag for your phone, tablet and chargers, your medications and maybe a blow-up neck pillow as well. Lastly, and most importantly, don't forget to bring your passport, travel documents and your bank cards.
Do not pack the following items in your hand luggage:
  • Pack all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your pocket knife, and products which are explosive or flammable, such as flares, bleaching agents and matches, are also restricted.
What to wear on a flight:
  • The aisles of an airplane aren't the place for a fashion parade. Wear layers and opt for shoes that are enclosed, flat and easy to take on and off.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To minimize your risk on board, drink lots of water, consider wearing compression socks or tights and keep your feet and legs moving.
How to get through airport security fast when flying to Round Lake?
The secret is to be well prepared before you arrive at the security gate. That way, you'll be hopping onto that plane to Round Lake in the blink of an eye. Follow these tips and get your trip off to a flying start:
  • Airport security personnel first need to determine that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to beep. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • Electronic devices like laptops and phones will also have to go through the machine for inspection. No need to worry though, you'll be back online soon enough.
  • Any gels or liquids, such as perfume or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • There's a possibility that you'll be required to take your shoes off for scanning, so wearing lightweight sneakers is always a wise idea.
  • Pocket knives and other sharp items are not allowed in the cabin. They'll be seized at security, so put them in your checked luggage.
