What are some of the general tips for travelers to San Diego County during the COVID-19 outbreak?
With new COVID-19 rules and measures in place, travel looks a little different at present. Here's what you need to know before you pack your bags for San Diego County:
  • Find out if any travel restrictions apply to your origin and destination before locking in your flight. Also check if there are any special conditions you'll need to follow on arrival, such as proof of a negative COVID-19 test.
  • Wear a face mask even during airport screening. A TSA employee will ask you to temporarily lower your mask to verify your identity.
  • To reduce the risk of cross-contamination, place your boarding pass on the scanner yourself and then hold it up for inspection. Do not hand your boarding pass directly to a TSA officer.
  • You're allowed to take one container of hand sanitizer up to 12 oz (350 ml) in your hand luggage. This will need to be removed for X-ray scanning.
  • Put any personal items (keys, wallet and phone) in your carry-on instead of a bin to reduce handling during screening.
  • If you're bringing food through the security checkpoint, place it in a clear plastic bag and then into a screening bin. This lessens the likelihood that a TSA agent will need to touch your food container or carry-on bag for inspection.
