No doubt.
But in all honesty, yes Tiger is well known for having terrible on time performance in the past, but that is the past. There's been a lot of changes there and it's a much different airline from what it was.
With lower cancellation rates and at most times better OTP than Jetstar (if you consider the network size and fleet size of both, it's certainly no easy task keeping those figures where they are for Tiger), maybe it's time to give it a rest?
Anyway, what does a 737 painted in Tiger colours have to do with improving their OTP anyway?
