Delta Air Lines says it will soon have a lapel pin to identify its employees who know sign language. Delta is the first U.S. airline to offer this option to add the language bar as an option for employees who know any of the more than 300 sign languages in the world.

Delta CEO Ed Bastian shared the news with a video on his LinkedIn page. "Our mission is to connect the world, which starts with making travel easier for all people," said Bastian. "It's a small step on our journey, but a powerful change as we seek to make the world a smaller, more inclusive place."

Delta says the initiative came to life as a direct result of feedback from Delta's customers, ABLE Disability Business Resource Group for employees and Advisory Board on Disability. Customers can expect to see uniformed employees sporting the new language bars later this fall.
