As a rule of thumb, the MCT is 60 minutes between domestic flights, 90 minutes between international flights, but it's not the same for all airports and in all situations.
Is a 1 hour layover on an international flight enough?
For international layover flights booked on one airline, two hours is often recommended to make your connection. For international flights on different airlines, the connection time will need to be even greater as you may have to change terminals between the two flights.
