That’s confusing. FT mentions 45mins for D-I, and 1:30 for I-D.
I have found other flights on the AA website with the connection to the AA73 under 90 mins (1:15, 1:11 etc). So MCT must be under 90 mins.
Ignoring all the suppressed entries, EF has:
STANDARD.D/D...D/I...I/D...I/I.
ONLINE 1.10 1.30 2.00 2.00
OFFLINE 1.10 1.30 2.00 2.00

AA-AA DI .40
So other than a host of flights to Canada, AA-AA DI MCT is 40 minutes. The 1 hour 30 minutes is the airport standard, applicable if the airlines don't have other specifics.
