|Ceased operations||1956 - Merger with Eastern Air Lines|
It was founded as Canadian Colonial Airways on 6 March 1928 to operate Foreign Air Mail Route No. 1 (FAM-1) from New York to Montreal via Albany, New York. Services began to Canada on 1 October 1928. The Fairchild FC-2 was among the aircraft types used. After acquisition by a group of investors, the airline was renamed Colonial Airlines on 1 May 1942.
The airline was awarded a route from Washington DC to Montreal and Ottawa on 10 August 1945, followed by routes to Bermuda in May 1946. Scheduled flights to the latter began on 1 August 1947. The shorter routes were operated by Douglas DC-3s and the longer routes by Douglas DC-4s.
By 1956, Colonial's executive offices were on Park Avenue in New York City and it was flying several routes including five daily nonstop DC-4 flights between LGA and Montreal. It also operated a nonstop DC-4 flight departing LGA at 11 am EST to Bermuda, arriving at Kindley Field 3:35 pm AST, with a "full course hot meal" served en route, its timetables advertised. It also offered a DC-3 puddle jumper flight from LGA making an 11:50 am Monday–Friday flag stop at Poughkeepsie's Dutchess County Airport en route to Montreal and Ottawa, Canada, with intermediate stops at Albany, New York, Rutland, Vermont, and Burlington, Vermont.
Merger with Eastern Air Lines
The airline operated for a period of five years during which a fierce competition was fought for its control between Eastern Air Lines and National Airlines. After several reversals of government policy, Eastern Airlines emerged as the acquirer and the operational merger took place on 1 June 1956. A few years following the merger, many of the Colonial's more rural destinations were deleted from Eastern's route network.
