Airdrie's hopes of a third-placed League One finish are hanging by a thread, going into the last game of the season at Edinburgh next Saturday, after they fell to a first defeat in eight games.
Clinical Queen of the South despatched them with two goals inside two first-half minutes and a stunning free kick with eight minutes left.
It's now only goal-difference separating Airdrie from Alloa Athletic, who as things stand will face either Championship second-bottom side Cove Rangers or Hamilton Accies in their play-off semi-final.
