AM flight with a Grande Americano freshly brewed from Starbucks. Put down tray from seat in-front, place full cup on tray, start to put bags in overhead and passenger in seat in-front throws himself into the seat causing entire cup to somersault directly into my seat. Entire seat cushion soaked through.

FA comes by with blanket and we try and soak up as much of the mess as possible. Still squishy. I keep eyeing the seat and wondering do I have to sit in it the entire flight.

Then FA becomes heroine - she comes back with an entire new seat bottom and we switch them out. Problem miraculously solved!
