Doing pretty swell, until real life took over & I had to cease ops & give others my slot if they wanted to participate.
I did find that I could run a 747-100 from DFW-LGA. It was listed as an available a/c & I was able to put it on the route. But for the sake of reality I took it off the route & put a couple of 727's on it.
Also Hartford/Bradley was mispelled.
Hope that is helpful----I think it was in the new real world that started in 1970.
