Nice sale from Tijuana to Mexico City with Aeromexico on a very scenic route: TIJ-GDL-MTY-MEX-TIJ. Here is a sample over Memorial Day weekend which allows you to fly almost the entire Aeromexico fleet with Boeing 737, 737MAX, 787 and an Embraer 195 and spend a day in Mexico City and one in Monterrey.
This scenic route would earn 5199 MQMs 1386 MQDs 7.07 MQD Ratio while Delta Diamond members would obtain 15250 RDMs, Platinum 12478 RDMs, Gold 11091 RDMs, Silver 9705 RDMs, Base 6932 RDMs
This fare works great for Delta flyers in Southern California as it is easy to access Tijuana Airport from San Diego via the Cross Border Xpress (CBX) which is an airport terminal located on the United States side of the border making it easy to fly out of Tijuana Airport.
