I go there once a month or so. Pretty good service, excellent for Mexico...I've learned to lie to them and tell them you are departing 30 minutes before you actually plan to. They have the typical Mexican obsession with systems, carbon copies, rubber stamps, and other BS paperwork. It takes them an extra 30 minutes just to sort out all of their internal crap to let you pay and be on your way...My flight plan Thursday had 7 rubber stamps on it when they finally handed it to me. i could hardly read it.
