Impossible turnaround time scheduling?

So I’m checking out AA’s flight schedule between MIA and MCO. The first flight from MIA to MCO departs 6:54am and arrives at MCO at a “scheduled” time of 8:07am (Flight 2537). But then that same 737 is scheduled to depart MCO for MIA at 8:15 (Flight 2537). I’m confused; is AA depending on that plane to arrive 20 minutes earlier than scheduled, giving it enough time for a 35-40 turn? Or are they using different equipment altogether but using the same flight number? Sorry if it’s a stupid question guys.

Looking at FR24, it isn't the same flight number, and the tails are different.

MIA-MCO in the morning is AA463, not AA2537.

On 9 May, AA463 was operated by N306RC, which has had no further movements since then. https://www.flightradar24.com/data/aircraft/n306rc

AA2537 was operated by N303RG, which arrived from MIA as AA2188 at 2350 local on 8 May. It then continued from MIA to TPA as AA445, departing at 1025 local. https://www.flightradar24.com/data/aircraft/n303rg

Sdmccray1984, What date are you looking at? Based on OAG data for the remainder of this month, the first flight from Miami to Orlando is AA 1712 departing MIA at 0835 and arriving MCO at 0946. Today, the aircraft that operated that flight N908NN continued to Charlotte as Flight AA 1597.

The information you have for AA2537 MIA - MCO may be in error or the times and/or flight number may have recently changed.

I cannot speak for AA, but at my operator, the network and planning division would not schedule an aircraft turn that short--in the example you gave above, 8 minutes. They would not depend, or hope, for favorable conditions to exist every day so as to provide for an on-time operation.

Our business clients--both cargo shippers and major companies which have significant contracts with us for premium business travel--look at Department of Transportation "on-time" data, as well as other parameters, very closely before they award contracts to airlines, so it is in our best interest to schedule block times and turn times as realistically as possible. These companies continually monitor the data and will occasionally choose not to renew a contract and award business to another air carrier if the original airline is not meeting their requirements.

and yes, you could assign a different aircraft to operate the return trip with the same flight number, although I have rarely seen it done this way. Occasionally, yes, but not routinely.

In a corollary to Stein’s Law, that which is impossible won’t happen.

Off topic, at one point intime TG scheduled a BKK-BNE-BKK 777-300 to be turned around in BNE in just over an hour... full cabin cleaning, catering, pax debarking and boarding for the return... no guesses how long that schedule lasted.

Aggressive but possible. We regularly turn around widebodies in 60-70 minutes.

It's much easier to do in countries with low pay- just add more workers to clean. In the TG BNE example above, it just wasn't possible. NZ had a similar 777 turnaround, but with significantly less catering and cleaning required so it was achievable.
