What are some of the general tips for travelers to Tri-Cities during the COVID-19 outbreak?
The COVID-19 outbreak may have changed the way we travel, but it hasn't dampened our enthusiasm for exploring. Here are a few tips on how to cope with the new challenges of traveling:
  • Before locking in your flight, see if any travel restrictions or bans apply — in both your origin and destination. Get the latest updates by reviewing government travel advisories.
  • When you pass through airport checkpoints, do not remove your face mask. You will be asked to lower it briefly for ID purposes. Travelers who refuse to wear a face mask may be fined and denied entry.
  • Avoid handing your boarding pass (electronic or paper) directly to a TSA employee. Rather, position the pass on the reader and then hold it up for the agent to visually inspect it.
  • You are now allowed to take one container of hand sanitizer up to 12 oz (350 ml) in your hand luggage. This will need to be taken out for screening.
  • Empty your personal items from your pocket, like your small change and phone, and place them in your carry-on rather than into bins. This will minimize handling during screening.
  • If you're bringing food through security screening, put it in a clear plastic bag and then into a scanning bin. This lessens the likelihood that a TSA agent will need to handle your food container or carry-on bag for closer inspection.
