The 'Ton scored once in the first half through David O'Brian before sweeping to a 4-0 lead by the 71st minute thanks to an Allan Jenkins double and one from Brian Graham.
Second Division Airdrie hit back twice through Gary Mackay-Steven and Sally Scott but their comeback was made difficult when Eddie Forrest was sent off nine minutes from time.
Morton wrapped up proceedings when Carrol Monti converted from the ensuing penalty to enable his side to run out 5-2 winners.
Allan Moore's side will now meet Premier League outfit Inverness Caledonian Thistle in the fifth round on February 5.
