I got citibank jet previlege card and when I first received my statement I was shocked to see the interest charges they put, actually other banks give interest free period, they have nothing like that, ur interest is charged from the first day you use your card, so basically the due date things is useless for this card, because whether you use 5 rs. or 15, 000 rs. the interest is counted only, so better if you have this card, use your card at one go and pay the interest.
the good part is that I travel by jet airways so I get miles using this card, so if you travel by air and sometimes you take jet airways, your card will start to collect jet miles, which can be redemed or even if you stay at some hotels which are listed by them you get jet miles, also using 100 rs. from your card you earn jet miles, all this miles collected can be used later in future.
also its a photo card, so can be used for ur identity proof , it also carries your signature printed in front only, look wise the card is really nice.
