The Transportation Security Administration today will start using modified procedures to screen elderly travelers at airports in Portland, Denver, Chicago and Orlando. Travelers older than 75 will no longer have to remove their shoes or jackets. However, the TSA noted that screening for older travelers with medical devices will not change. "These passengers will be afforded an additional pass through advanced imaging technology to resolve anomalies. These changes in protocol could ultimately reduce -- though not eliminate -- pat-downs of travelers 75 and older that would have otherwise been conducted to resolve anomalies," the TSA said in statement.
