The wiki on this thread states:
What is the domestic to domestic or to international Minimum Connection Time (MCT)?
The minimum connect time at ORD, domestic to domestic or international, is 0:40 minutes. Domestic to international is easy if your international flight departs the AA terminal, but domestic to International terminal is comfortably done in 2:00 (not the official MCT, 1:15), because of the lack of connectedness between terminals. International arrival at Terminal 5 with flight departing Terminal 3, Global Entry is likely to allow 2:00 or even less, but non-U.S. or Canadian passport holders with checked baggage might use 3:00 as a better guideline.
That confused me last month, since someone said 35 is legal for D2D (not 40). I'm happy to edit the wiki so others don't run into that - any other disclaimers to account for there or specific rules to call out besides just changing that line to 35?
