Spending is usually 10-20k max per month for us bro. Any big purchase like electronics will increase the spends, that's it. Nothing much!
Need the CC for unlimited lounge and better reward points. That's it.
Even if we get DCB PVC, we wont be able to reach the max cap of 7500/ day. But, yeah, if getting metal, then will go for metal.
Also, 80k/ month is occasionally possible and is better than no milestone at all in Infinia. Moreover, chances of them giving us Infinia are less as our spends are not much.
I'd any day prefer Infinia if given LTF and without much hassle.
FYI, Holding Regalia currently. We wont be able to recover the fee amount as it would be primarily used by my dad for household spends, so going with LTF makes sense imho.
