Amex Platinum vs Delta Reserve: which lounge card fits?

The real difference#

Both cards touch Delta Sky Club and Centurion Lounge, but the conditions differ. On Delta Reserve, both grants require you to be flying Delta that same day. On Amex Platinum, Centurion access has no such string attached, and only the Sky Club grant carries the same-day Delta rule.

Beyond that, the Platinum adds three networks the Delta card lacks: Priority Pass, Plaza Premium, and Escape Lounges. Those are what keep the Platinum useful on days you are not flying Delta.

Where each card has the edge#

Amex Platinum lists an $895 annual fee; Delta Reserve lists $650. The extra $245 buys unconditional Centurion access plus the three additional networks, which is a strong case for the Platinum for anyone who flies more than one airline or travels abroad.

Delta Reserve is the tighter fit for a Delta loyalist who rarely leaves the airline. In that pattern the lounge experience on the two cards looks nearly the same at Delta hubs, and the cheaper card wins. The gap opens up on international trips, at non-Delta airports, and with traveling companions, where the Platinum's broader networks give more doors to try.

Make the choice from real trips#

I'd list your next three airports along with the airline you would fly from each, then compare which lounges each card would open under those conditions. Verify enrollment in each network, the same-day boarding-pass rule, any visit limits, and guest charges. American Express can change either card, so confirm the current terms before applying. Our methodology explains how we record conditional access.

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.
