But on the return leg on that route, I take the AA flight from Curacao to Miami and have 2 hours and 35 minutes to connect to the return flight to London. It would be helpful if they allow me to book the luggage from Curacao to London.
This is exactly the situation I had, Curacao - Miami - DFW... The 2 1/2 hours in Miami was barely enough time to get through all the crap in Miami before boarding my flight to DFW. I think it also depends on how many other international flights are coming in at the same time and have to go through immigration/customs. My flights from Curacao - Miami - DFW were all on the same airline (American).
Good luck...
