Which airline? Maybe a typo for AA Platinum Pro (often abbreviated Plat Pro) or old name for UA status level?

I can’t address your specific questions, I will offer that some airline and hotel programs have limitations on status matches, i.e. once every 5 years or once per lifetime. So if you’re not expecting much travel during fellowship, it might not be the most opportune time for a status match in terms of timing AND utilization.

FWIW, years ago United, Hilton and Hyatt were very gracious in extending statuses and also expiration dates of various awards for more than a year after no (commercial domestic*) travelling for 8 months due to Navy Reserve mobilization to Afghanistan. Statuses and awards were due to expire in the middle of MOB, I requested extensions prior to departing, all 3 programs told me to ask again upon return so my requests ended up occurring several months after expirations. I don’t recall if any required proof of MOB. My requests for those extensions were excellent examples of “never hurts to ask, worst they can do is say ‘no’, give them an opportunity to say ‘yes’.”

Wish you well for the fellowship. (FWIW, during my residency after 8 years as an attending in the Navy, I often felt as if I had been relegated to “2nd class citizen”. I don’t think that’s the case with most fellowships and it’s probably specialty dependent.)

(* Not including ~25,000 BIS miles on various military charter and transport aircraft, and sharing a small lodging room with a complete stranger who snored almost as loud as a chain saw, and sharing bathrooms with another 40 strangers. For a 50 something year old FF nutjob with multiple elite statuses all that was almost a “fate worse than death” and a large contributor to my personal dissatisfaction with MOB.)
