Maddie Peters said she had never spilled a drink on a passenger in her four years of working as a stewardess for American Airlines.

That's why she was "mortified" when a passenger bumped her and made her spill an entire tray on another passenger.

But that got even worse after she realized who the passenger was — the CEO of American Airlines.

Peters posted the story of her little accident on her Instagram account. She says that the crew was tipped off about CEO Doug Parker being on board the flight from Phoenix to Dallas.

"We knew he was going to be on board and had to be on our best behavior," Peters said to NBC News.

She said she dropped the tray and the drinks splashed on Parker and on herself.

"I wanted to drop dead right there," she said in the Instagram post.

Parker laughed off the accident, and she says that he went to the galley to reassure her that everything was all right.

She says that she asked him if she was fired.

"Of course not!" he responded.

"When he was getting off the plane he told me he'd never forget me," she joked, "guess that's a good thing, right?"
