So, i have an opportunity to upgrade my cabin class from Economy to Business for my Delhi to Leh flight. Is this a good deal?

Hello People

I received an upgrade plus email yesterday to upgrade from Economy to Premium Economy or Business Class. The upgrade offer was too good to let go but when I tried to upgrade, it was asking only for the Credit Card details and I don't have a Credit Card.

The question is how can I upgrade my cabin class for the same offered price?

TIA
