It's a passenger name record which is created when booking a flight.

As to how you find out the info if you aren't a travel agent I'm afraid I don't know, sorry.

Answer 2

Yeah, the letters stand for "Passenger Name Record," but what it refers to is the series of letters and/or numerals also referred to as "confirmation number" or "booking number."
