Given its title, I'm a bit surprised not to find anything about MCT in the Wiki or by searching the thread — apologies if there' something hidden in the middle of it. I'm booked on an itinerary with 42 minutes of connection time. According to EF, the MCT is 45 minutes, and Tripit also flagged it to me as an unsafe connection. However, I phoned AA, and the agent told me that for some flight combinations, the MCT is as low as 35 minutes — is this correct?
