This Convair Metropolitan was an upgrade in equipment for Southern Ontario commuters when Great Lakes bought two aircraft from Swissair in 1969. Three ex- Linjeflyg and one ex-Luftwaffe 440 followed before the airline switched to Convair 580s beginning in 1976.

In 1969, Great Lakes Airlines began upgrading their fleet with two Convair 440s bought from Swissair. Four more 440s were brought on-line before the airline switched to Convair 580s around 1976. This is former HB-IMK "Neuchatal", that was originally flown in the basic Swissair colors, until the next aircraft from Linjeflyg introduced a new color scheme based on that airline's cheat lines. To Key Air Lines in 1976as N30KA, the aircraft eventually sat out it's days in Florida after the mid 90s. The registration was cancelled in 2012.

Previously HB-IMK with Swissair, in case the livery looks familiar.
