I have done my booking from Kingfisher airlines on 24th february 2011, from kandla to mumbai dated 9th march for 2 adults.
I paid 11764/- (kingfisher airline PNR is LAJBYN)

On 26th february when i am checking for same destination, same date rate is decresed (i.e. 10764)

When I tried to talk to kingfisher airlines customer care, they rudly replied that this is the way we charge :(

I felt insulting when i talked to them, I will never never use service of kingfisher in future and i am going to post this in so many online forums so other flyers also aware about kingfisher's behaviour
