Lounges each card opens, busiest airports first.
And 391 more airports; each card's page lists them all.
The real difference#
For lounge purposes these two HDFC Bank cards are the same product. HDFC Infinia and Diners Club Black each unlock a single network in Lounge Frog's data: Priority Pass. Neither grant carries a same-day flight condition or a visit cap in our records.
Because the network is identical, any Priority Pass lounge in India or abroad opens for one card exactly as it does for the other. There is no airport where the Infinia gets you in and the Diners Club Black does not, or the reverse.
Where each card has the edge#
Infinia Metal Edition lists an annual fee of ₹12,500; Diners Club Black Metal Edition lists ₹10,000. With matching lounge access, the Diners Club Black is ₹2,500 cheaper for the same doors. Whether the Infinia's higher fee is justified rests on benefits Lounge Frog does not track.
One practical wrinkle is acceptance: Diners Club and the Infinia run on different card networks, which can matter for everyday spending abroad, though it does not change lounge entry since both route through Priority Pass. For home-airport use, international connections, and guests, the two cards should behave the same way at the lounge desk.
How I'd make the choice#
Look up your next three airports and confirm a Priority Pass lounge sits airside in the terminal you use; if none does, neither card solves the lounge problem. Then check enrollment in Priority Pass, whether a boarding pass is checked at entry, any visit limits, and guest charges. HDFC Bank can revise either card, so verify the current terms before applying. Our methodology explains how we record card grants.
Putting this into practice#
I would start this comparison with the next few trips already likely to happen. For each card, I'd list the lounges that fit those airports and departure areas, then remove locations that would require an impractical detour. That is a more useful comparison than adding up every lounge in a worldwide network, most of which may never help with those trips.
Guest rules deserve their own line in the calculation. A card that works well for one person can be a different proposition for a couple or family. I'd compare the cost for the party that actually travels, including any separate membership or additional-card charge. I would not assume a benefit on one version of a card applies to another version.
The annual fee is only part of the decision. I would value other benefits at the amount I would realistically use, rather than automatically count a credit at face value. A benefit that requires a booking I would not otherwise make does not reduce my costs in the same way as money saved on an existing plan.
The trade-offs I would check#
I would check enrollment and the credential needed at reception before relying on either card. Some benefits are used through a separate membership rather than by showing the payment card. The issuer's current terms should settle the visit allowance, guest treatment and any airline or fare restriction. The comparison above helps identify the differences worth checking.
