The TSA has changed its security procedures to minimize handling of documents by agents in response to the pandemic. Changes have begun to be implemented and will be at all airport checkpoints by mid-June. Travelers will no longer hand their boarding passes to a TSA agent at the document checkpoint. Instead, they will place the boarding passes on a reader themselves. After it’s scanned, travelers should hold their boarding passes and move them toward a TSA officer, who will visually inspect them. This reduces physical handling. At the X-ray checkpoint, passengers with carry-on food items must put them in a clear plastic bag and place that bag into a bin. Because food can trigger an alarm during the screening, separating the food from the carry-on bag reduces the likelihood that a TSA officer will have to open the carry-on bag and remove the food for closer inspection. This requirement also fosters social distancing and reduces potential for cross-contamination, officials said. TSA PreCheck members do not need to remove items from their bags. In response to COVID-19, TSA will allow each passenger to carry on one liquid hand sanitizer container, up to 12 ounces. Passengers are required to remove the hand sanitizer from the carry-on bag before X-ray screening. Other liquids are still restricted to 3.4-ounce containers.
