Airdrie were left on the wrong side of Championship play-off history again, as a Simon Murray penalty gave Queen's Park a narrow win at New Broomfield that sees them promoted instead.
The Diamonds had taken the lead through Rhys McCabe's superb free kick, but Queen's Park levelled through Connor Smith.
They bagged their winner in the second period of extra-time when Dylan Easton fouled Simon Murray and the former Dundee United and Hibs striker dusted himself down before sending his side up to the Championship.
