When you’re booking online always bear in mind the booking and travel period in order to avail the promo fare. Like in this promo the booking period is only until Nov. 8 2012, and the Travel period is only between June 1 2013-September 2013. You should do you search within these periods. That’s how I was able to come up P2122 (ALL-IN fare). Otherwise you will not be able to avail the promo fare.
