The air carriers certainly have taken advantage of the diminished competition flying from the USA into Mexico. Mexicana's bankruptcy was a God-send for them. Then there are those other fees. It all adds-up quickly. For my Chicago to Mexico City and back flights, the fare has about doubled in the past two years. Mexicana will be back flying, probably by the end of this month or early in January. Probably only 3 or 4 USA cities will be served then, but I'm certain Chicago will be one of them ... and I'm hoping Mexicans starts a fare war of sorts (a downward spiral). Mexican budget carrier Volaris will start serving the Chicago market, next week. The recertification as a Cat. 1 is important, for many reasons.
