"I noticed that I was missing my wallet, which had 60 dollars cash and a check for about $400 in it," Shamatt explained.

He didn't ever expect to see that wallet or money ever again, but he received a package in the mail days later with his wallet and a letter.

"Hunter, found this on the Frontier Flight from Omaha to Denver, Row 12 Seat F, wedged between the seat and the wall. Thought you might want it back," the letter read.

But the mystery man – only identified by the initials T.B. in the letter – didn’t stop there.

"I rounded your cash up to an even $100 so you could celebrate having your wallet back. Have fun,” the letter concluded.
