Best credit card for air travel

[RM95]

I'm trying to enter the airmiles game and I have almost zero knowledge of how it works (miles accrual/transfer). Can someone suggest me a good credit card that I can use as a primary card and accrue points? I have 2 intl travel plans next year, planning ahead for the same.

Also, links to articles explaining more about airmiles will also be much appreciated.

Salaried. Income ~2L pm.
Credit history of ~5 years (Axis Neo, Bob Premier, SBI Vistara Prime, ICICI AmazonPay)

If someone is only interested in booking flights, is DCB just as good as Infinia?

Yes flights and hotels give same bonus rp as Infinia

Amex Platinum travel card. Accumulate the reward points, convert to Virgin/ Marriott during transfer Bonus and use.
Axis Atlas is also a good alternative.
