- 411
Side by side
Both include Priority Pass.
Airport by airport
Lounges each card opens, busiest airports first.
And 407 more airports; each card's page lists them all.
The real difference#
Altitude Reserve unlocks a single network, Priority Pass, and Lounge Frog's data flags that access as limited to a set number of visits per year. Once those visits are used, the card no longer opens lounge doors until the allowance resets.
Amex Platinum includes Priority Pass without that cap and stacks Centurion Lounge, Plaza Premium, Escape Lounges, and Delta Sky Club on top. The Sky Club entry applies only when you are flying Delta the same day. So the overlap between the two cards is Priority Pass, but even that overlap is uneven because one side is metered.
Where each card has the edge#
The fee gap is wide: $895 for Amex Platinum against $400 for Altitude Reserve. For an occasional traveler who takes a handful of trips a year, the capped Priority Pass on Altitude Reserve may cover every lounge visit they would make anyway, and the savings are real.
Amex Platinum earns its fee when you fly often enough to blow through a visit cap, when your home airport has a Centurion or Escape lounge, or when Delta is your main airline. It is also the stronger pick for international itineraries where Plaza Premium and Priority Pass together give more fallbacks. Frequent guests push the same direction, since every extra person burns through a limited allowance faster.
How I'd make the choice#
Count your realistic lounge visits for the coming year, then map your next three airports on each card page. Confirm enrollment, the same-day boarding-pass rule for Sky Club, the exact Altitude Reserve visit cap, and guest fees. Card terms change, so check current details with each issuer before applying. See our methodology for how access is recorded.
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.
