What are some of the general tips for travellers to Tri-Cities during the COVID-19 outbreak?
With the continuation of the COVID-19 outbreak, travelling now comes with a few extra challenges. Keep in mind the following information before hopping on your flight to Tri-Cities:
  • Before committing to anything, see if any travel restrictions apply — in both your origin and destination. Get up-to-date information by checking government travel advisories.
  • Keep your face mask on even during airport screening. A TSA officer will require you to temporarily lower your mask to verify your identity.
  • Rather than handing a TSA officer your boarding pass, place it directly on the reader yourself. Then, hold it up for inspection.
  • TSA is now allowing passengers to take one container of hand sanitizer, up to 12 oz (350 ml) in size, in carry-on baggage. This will have to be removed from your bag at the X-ray machine for screening.
  • Place any personal items (e.g, keys, phone and wallet) in your carry-on instead of a bin to minimize handling during screening.
  • Separate any food you have for X-ray scanning. Putting it in a clear plastic bag and into a bin reduces the need for a TSA officer to handle and inspect your belongings.
