A friend of mine contacted me with some family history. His grandfather was part owner of a small airline in Niagara Falls, New York in the 20's. It was called Frontier Airways, Inc.- not to be confused with the Frontier Airlines of the 50's and later. The letterhead he found advertised sight-seeing, flying lessons and photography. They may have had three aircraft, possibly including a Travel Air 2000 - NC-6087. Do any of you airliner and civil enthusiasts have any info on this company? Thanks. Nick Filippone
