I saw this web site advertised in Computer Pilot magazine but I haven’t seen
anyone mention it here in this forum.
Check this out….http://www.flightlookup.com/
Just type in your point of departure and your proposed destination. For any
given date you will get a list of all the airline flight numbers, and the
aircraft types in use.
At the risk of sounding like Krusty the Clown (“I heartily endorse this
product
or service”) I can tell you that I use it all the time now!

Cheers,

Bill
