Nice sale from Tijuana to New York with Aeromexico... 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...
You can schedule some long layovers in Mexico City which would allow you to explore the city since you can reach the Zocalo via metro, 45 minutes to an hour both ways and see the Cathedral, National Palace and Rivera Murals, and the Templo Mayor or if you have some more time you can venture out to Teotihuacán which is an ancient Mesoamerican city located 30 miles (50 km) northeast of modern-day Mexico City.
