I recall there being much more frequent service a couple of years ago when we were considering flying there from Texas. Since then tourism in and around ACA has declined dramatically in reaction to drug cartel violence. Many cruise companies have completely cut Mexico's western coast from their schedules.
Yes, that sounds like a correct reasoning. Never knew the reportings of violence had such an effect on tourism in that area. I am going to recommend some similar (with better *A availability) destinations to them however I think their hearts are set on ACA. Thanks
