Taking the Aero Servicios bus only makes sense if you are traveling solo. If you are two or more a taxi is more economical because it doesn't cost more per person. I took Aero Servicios because I was traveling alone and had extra time. Then from the old airport to my hotel the taxi was another $7. A taxi costs $25 per trip and will be more time efficient. The old airport has a lot of taxis waiting when the Aero Servicios buses get in.
