The terror attacks on 9/11 had a lasting impact on air travel. Big changes were implemented, affecting both airports and airlines like Delta. Security measures were put in place, including Transportation Security Administration screening, which requires a ticket or identification to pass through.

Before 9/11, security was less strict, allowing people to move more freely in airports. For example, individuals could run underneath terminals without restriction.
