NY Air did not exist in 1979, I think they began operations in the early 1980s are flew from LGA
, they did try some other destinations but Syracuse, to my knowledge was not one of them.
In 1979, a red airplane would suggest Allegheny, (the old name of US Airways), which had a red/burgudy livery and did fly between NYC and Syracuse (not sure about JFK
, but certainly LGA
)......DC9s, and BAC 111s were on the route.
