Had to take an unplanned flight with 30 family members to ZAC (Zacatecas) from TIJ (Tijuana). Tijuana International Airport is very nice. Security is pretty stringent. They have a couple of check points with army officers. Check in was not the best but we made it on the plane on time. The plane was an A320. Clean. On- board staff nice. They handed out alcohol soda water and chips. The flight was smooth and arrived at ZAC on time. Check in on the return flight from ZAC to TIJ was not good. They apparently sell some sort of fast pass check in which delayed those that did not want to pay for that service by about an hour as they got first priority. We made it on a packed plane. Flight crew was great. Arrived on time. I would fly them again. They are very reasonably priced and offer great service.
