What are some of the general tips for travellers to Quad Cities during the COVID-19 outbreak?
COVID-19 has led to big changes to how we travel. If you're planning a holiday in Quad Cities, the following tips will help you navigate this new travelling reality:
  • Investigate if any travel restrictions apply to your origin and destination before booking. Also check if there are any requirements you'll need to follow on arrival, such as proof of a negative COVID-19 test.
  • When you go through airport screening, do not remove your face mask. You will be asked to lower it briefly for identification purposes. Passengers who refuse to wear a face mask may be denied entry or boarding.
  • Instead of handing a TSA employee your boarding pass, position it directly on the scanner yourself. After that, hold it up for inspection.
  • One liquid hand sanitizer container is now permitted in your carry-on luggage. It must be no larger than 12 oz (350 ml), and you'll have to remove it from your bag at the X-ray machine for scanning.
  • Place any personal items (like your phone, wallet and keys) in your carry-on rather than a bin to minimize handling during screening.
  • Separate any food you're carrying for X-ray scanning. Placing it in a clear plastic bag and into a bin reduces the need for a TSA officer to touch and inspect your belongings.
