if this is too off topic, please feel free to delete, but I know there are some seasoned travelers here who can offer personal experience.

I am flying to Cancun from Detroit on Delta in Business Class. How early do I need to get to the airport?

Security Check-in Requirements for International Travel To/From Non-U.S. Cities
The recommended arrival time at the airport prior to departure of international flights is 3 hours. When traveling to/from a destination outside the United States, you must be checked in at least 60 minutes before your scheduled departure time and it is required that originating passengers be at the gate and ready to board at least 45 minutes before your scheduled departure time. This minimum requirement applies to all customers checking-in, with or without baggage. Customers who fail to complete the check-in procedures by these deadlines will not be able to travel on desired flights and change fees may apply.

I'm another fan of 3 hours for international flights.
