I booked a cheapo interjet ticket YYZ-MEX-CUN almost a year ago and now it is coming up. The schedule now has changed multiple times, with 1 hour 55 min connection at
T1 between 4:05am to 6am. Other than 1 jumbo from MUC landing at the same time and a few south american flights later in the hour, I dont see many other flights.

I've only transited through T2 on AM during such hour before. It was very quick at the custom and I was able to use the machine as Canadian without paper immigration forms.

Do you think I should keep the itinerary or take 4O's offer to move my CUN flight an hour later. Interjet left me a message to change the flight due to illegal connection but did not force me to change it when I called (other than I shall be responsible if I miss the connection). But I want to arrive in CUN early in order to catch my diving boat at noon.
