Partick extended their unbeaten league run to six games, but the draw still leaves them hovering above the relegation zone.
Thistle took the lead after 14-minutes, when Derek Fleming curled in a wind-assisted corner kick into the net.
Airdrie equalised 10 minutes later when Alan McManus headed in a David Dunn corner from six yards out.
Thistle almost scored at the death but Mark McGeown saved Armand One's goal-bound header.
