Air travel

Because of how air circulates and is filtered on airplanes, most viruses don't spread easily on flights. However, crowded flights make social distancing difficult. Plus, air travel involves spending time in security lines and airport terminals, which can bring you in close contact with other people.

The Transportation Security Administration (TSA) has increased cleaning and disinfecting of surfaces and equipment, including bins, at screening checkpoints. TSA has also made changes to the screening process:

• Travelers must wear masks during screening. However, TSA employees may ask travelers to adjust masks for identification purposes.
• Instead of handing boarding passes to TSA officers, travelers should place passes (paper or electronic) directly on the scanner and then hold them up for inspection.
• Each traveler may have one container of hand sanitizer up to 12 ounces (about 350 milliliters) in a carry-on bag. These containers will need to be taken out for screening.
• Personal items such as keys, wallets and phones should be placed in carry-on bags instead of bins. This reduces the handling of these items during screening.
• Food items should be transported in a plastic bag and placed in a bin for screening. Separating food from carry-on bags lessens the likelihood that screeners will need to open bags for inspection.

Be sure to wash your hands with soap and water for at least 20 seconds directly before and after going through screening.
