I have a business regalia for quite some time with a limit of 3lac, my usual spending on this card is around 5lac a year. At the start of this year for some reason my cc limit was enhanced to 8lac. upon realizing even on tax payments i receive points(there are transaction costs), i did pay 1-1.5 lacs for 5-6 months to acquire milestone benefits etc. I stopped using my cc for about 3 months now and got an upgrade over the weekend with first year free. I don't know if not using it helped or paying tax using this card helped. Either way something to try if anyone is in similar spending patterns
