Yep! This was my secret during Beta2. I used viscounts as my main aircraft having just over 60 before I replaced them with 737s. I was able to keep pace with other airlines using SE-210s and other jets.
I loved them and found it took 15 years for a true replacement to appear.
They have excellent speed, seating, fuel econo and decent range. Although the draw backs were extra crew and not in production.
In anycase, I'll be leaning on them again in my battle in JA #3
