The COVID-19 pandemic may have changed how we travel, but it hasn’t curbed our passion for exploring. Here are a few tips on how to cope with the new challenges of traveling:
Investigate if any restrictions apply to both your destination and origin. It may not be possible to travel depending on local circumstances, so remember to check before you book.
Wear a face mask even during airport screening. A TSA employee will require you to temporarily lower your mask for identification purposes.
Do not hand your boarding pass (paper or electronic) directly to a TSA officer. Instead, position your pass on the reader and then hold it up for inspection.
One container of liquid hand sanitizer is now allowed in your carry-on bag. It must not be larger than 12 oz (350 ml), and you’ll have to take it out of your bag for screening.
Empty everything from your pocket, like your keys, phone and wallet, and place them in your carry-on rather than into bins. This will reduce handling during screening.
If you want to take food on board, place it in a clear plastic bag and then into a scanning bin. This reduces the likelihood that a TSA agent will need to handle your food container or carry-on bag for inspection.
