Well, let's think about that. AC is the #1 tourist destination of Belize. The most important source of income for Belize is tourism. So it's logical to see that establishing a Cancun - Belize air connection will mostly be a Cancun - AC connection.
Now the only question is, will a direct to AC connection be established or will the government continue to require a stop at BZE prior to coming to AC?
If the goal (of the government) is increased tourism (which it is) then it certainly makes sense to make arriving as hassel free and economical as posible. AC is responsible for generating the majority of the tourism dollars therefore a direct to AC route is logical and not "a stupid idea".
