Before the "other three airlines" had their MEL-PER sales(which all started today, well DJ went on sale first) Tiger would have been the cheapest, but now they have been outdone cause of sales. Searching into 2009, there is MEL-PER on tiger for 89.95, noway you will ever get this on JQ/DJ anymoreAlso, this flight is possibly 70/80% full already, so that is what LCC do, up the ante. MEL-PER would be one of TT"s best performing routes (never experienced a flight on this route on Tiger, which is now 6 times, under 90%!)Tiger also do not follow JQ/DJ/QF's sales, Tiger will have a sales every week, or everyday of the year there is a Tiger sale. If JQ have a $1 sale to LST or ADL, TT wont follow, they stick to themselves.Their current sale at the moment isn't to bad though, those OOL prices are always unbelieveable
