How to determine lounge access of flight?

[tripwaffle]

Probably a dumb question, but is there a single source of truth for when one may wish to know what lounge(s) they have access to, for a specific airport + airline + fare class?

Ignoring all other factors such as airline status, credit cards, etc.

No not really.
There are website lounge finders for Star Alliance and One World etc but no one source of truth that I am aware of.

We have our own help desk thread for specific questions

There are so many lounges, so many nauces. You cannot ignore status. If TripWaffle I suspect general definitions with absolute disclaimer could be necessary.
For oneworld, here is a reasonably accurate source of truth.

Airport Lounges: oneworld Lounges & Airport Lounge Access

Enjoy airport lounge access at nearly 700 airport lounges worldwide through your oneworld Priority tier. Exceptions may apply.

Access can be based on elements such the Airline the PAX has status in, the travel class, ailien they are travelling on, the route etc.

Check out SIN for example,

Oof, sounding like a big can of worms.

LoungeBuddy (RIP) had the database of lounges around the world (and reviews). I think it had some access info also?

No idea why AMEX acquired it only to shut I down?

There are some startups trying to replace LoungeBuddy but I’ve not tried any in anger.
