I read the first edition of Professor Doganis' worthy tome just as easyJet was struggling into life. His book made no mention of low cost carriers! Stephen Shaw's book about marketing: Airline Marketing Management I found to be an excellent read.
It is interesting to compare how airlines are run worldwide; Southwest with it's belief in the importance of people and Ryanair/Jetstar who treat their employees in a manner reminiscent of the industrial revolution workhouses! Read widely and try to remember that, whilst correlation proves nothing, a happy crew will probably perform a little better than a dismally miserable crew (I cannot find a reference for that though).
