i sort of took a gamble on KK-taipei may 26-jun 2
return is RM407(RM105 go, RM302 back)
is it a good deal?...hopefully is school holiday
and somehow the tix frm 24th until 7th jun is more expensive than before and after that date
if before and after...RM238 is the cheapest for 2 way...thn after is RM289

kk(BKI) - taipei
for from may 24th till june 8th no more cheap tix...all sapu last promo
but before and after that period for the RM149 as advertised

and look what i saw when i went searching

if u see my post above
24th may till 8th june is expensive...cheap tix all gone
and from what i see, this promo sells whats leftover of the previous promo
the previous free promo which is the real one
i notice the 24th may till 8th june is selling more expensive than before and after that date
its cheap tix but if compared with before and after, its more expensive

this promo is selling whats leftover of the last promo(which is the real one)

i would say follow the price
but am not sure
because for the mid year holiday
when i look back to past year...some holiday are starting from june
not from end of may
when the last free promo, i kinda look at the whole 2 month and i found these 2 weeks...the price is a little higher than before and after
so i purchase it
meanwhile my relative also looking for mid year holiday bought 2 weeks later(which is after 8th june when they come back) and their total price, not sure is true or not..more expensive than what i paid
