Thank you for your service, Mr. DiLiberti.

The United gate attendants Googled the gentleman while he was waiting to board the flight from Boston to Chicago - they saw his veteran's cap and looked him up. They found out that he had over 100 jumps under his belt.

His name is Angelo DiLiberti. He says that he was inspired by Pearl Harbor and served in the Army during WWII. His career spanned over 33 years through the Korean and Vietnam wars, and he retired as a lieutenant colonel.

As passengers boarded and thanked him for his service, one passenger went above and beyond - Lisa Axelrod offered her first-class seat to him. The pilots also offered up their seats for a photo with DiLiberti.

*Note: United's Twitter feed incorrectly identified Lisa as one of the gate agents*
