IIRC, EK requires only 15k points for a round trip within India on Jet ..

From wht info I have till now, the advantages / disadvantages are as follows :

Advantages
EK
No fuel surchage on award tickets..

LH
More rdemption options from India to SE asia, Africa and less miles required for redemption.
Status holds good for 2 yrs

My main target is to earn miles while mostly flying Y and then redeem these for award tickets for personal travel..

Any advise for additions to the above will be appreciated

Thanks
Abhi
