I know this is old but I had been wondering the same thing for my upcoming trip. Glad I stumbled upon this post.If El Catey is your final destination then your best bet would be fly Miami Limo to either Dusseldorf or Toronto and and connect direct to El Catey, but might be quicker and cheaper to fly straight to SDQ and take a taxi to El Catey..
Kidding aside,,, At the moment I do not believe there are any direct flights from the USA to El Catey. Echos say that AA might be starting in Feb 09, Miami Airport Hotels.
Happy Holidays and have a safe and pleasant flight !
