It is my belief that Go have made a profit from start up quicker than both FR and EZY, in what can be arguably a more cut throat environment. Not bad going really.
as for the routes launched early, the research shows that most pax on FAO, AGP, and ALC are holiday makers, not last minute biz pax. it makes sense to launch sales early for these routes as the families of 5 that these routes serve like booking early so they can secure accomodation as well. It also gives Go a chance to sell seats to customers who might go thru tour operators instead.
anyone, thats my few thoughts, no doubt i'll get shouted down!!!
