Amex Platinum vs Morgan Stanley Platinum: which lounge card fits?

Nothing to split on lounges#

The Platinum Card and the Platinum Card from Morgan Stanley share an issuer, a fee and a lounge list. Both are American Express cards at $895 a year. Both unlock Priority Pass, the Centurion Lounge network, Plaza Premium, Escape Lounges and Delta Sky Club. The Delta access requires a same-day Delta flight on either card.

That is the whole lounge comparison. There is no network one has that the other lacks.

Where the choice really sits#

The Morgan Stanley card exists for people with a Morgan Stanley relationship. If that is you, it may be the tidier fit. If not, the standard Platinum is the card to apply for. Either way you walk into the same lounges.

One check before applying#

Pull up your next three departure airports and see which of the five programs has a lounge in your terminal. I'd confirm guest charges, visit caps and enrollment steps with American Express, since those are set by the issuer and programs. Lounge scores on this site follow the methodology page.

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.

For a frequent departure airport, I would put extra weight on the useful options that one card adds over the other. Two cards can share much of a network while differing at the one terminal that matters most. Conversely, an impressive exclusive lounge has little value to me when it sits at an airport outside my normal routes.

I would also separate eligibility for the card from the value of its benefits. A business product and a personal product can have different application requirements and account features. The lounge comparison does not answer those questions. Before applying, I would read the relevant issuer information and make sure the product itself suits the intended use.
