I've never heard of a major carrier having to hold job fairs to get pilot applicants either...
Jim
I went to a Northwest pilot job fair in I think it was 1983???
Also, I think most airlines have at one time or another actively recruited at Women In Aviation conventions and job fairs.
Plus, I believe ALPA would historically sponsor job fairs at airlines that were hiring, when there were members furloughed from other member airlines.
