Thanks for all the info. The reason I asked is that I got my 737 rating on a 737-100 some 22 yrs ago and am ready to retire early from my airline job. I just wanted to know what I might be qualified for in the Corporate World.

What made me wonder is that my A320 type is separate from my A330 type which is separate from an A340 type although the cockpits are basically the same.
