My wife has a Regalia card along with Tata Neu Infinity with common limit. Spends are bare minimum as she has add-on cards of my DCB Metal, SBI Elite and Magnus. In fact, she does not use Regalia at all, and lounge access is through the add-on cards. There is also no point upgrading Regalia to any higher card. Should I just make her close the card and retain only Tata Neu?
