What are some of the general tips for travelers to Southern Illinois during the COVID-19 outbreak?
With new COVID-19 rules and measures to adhere to, travel looks a bit different at present. Here are some useful things to know before you hop on that plane to Southern Illinois:
  • Research the rules and restrictions in both your origin and destination. You may not be able to travel depending on local circumstances, so make sure you check before you lock in your flight.
  • Wear a face mask during airport screening. A TSA employee will ask you to temporarily lower your mask for ID purposes.
  • To minimize the risk of cross-contamination, place your boarding pass on the scanner yourself and then hold it up for inspection. Do not hand your pass directly to a TSA officer.
  • One liquid hand sanitizer container is now allowed in your carry-on baggage. It must be no larger than 12 oz (350 ml), and you'll need to take it out of your bag for X-ray scanning.
  • To reduce handling during the screening process, place items such as your phone, keys and wallet into your carry-on rather than the bins.
  • Transport your food items in a clear plastic bag and also put them in a screening bin. Keeping your food separate from your carry-on makes it less likely that a TSA agent will need to open your bag for inspection.
