In all my years of flying the only real spill disaster I experience was just last November, when the plane hit turbulence just as the FA carrying a tray of hot coffee was walking by, dumping a significant amount on me and my laptop. Luckily almost all of it hit my laptop, jacket and tie, sparing me from getting burned. All of eventually cleaned up just fine.

Was a bit of a blessing in disguise. I was going to a business meeting in LA and a tie and jacket would have made me terribly over-dressed. Even the board members were wearing their shirts unbuttoned.
