Delta fares to Mexico

We haven't seen any truly spectacular fares to Mexico in a while, but these Delta sale fares are the lowest in the market for nonstop flights. They seem deceptively low at first glance since they're listed as one-ways before taxes. For some reason, taxes to Mexico are quite high, usually over $100 on a round-trip ticket. Book these fares by June 30, and note the blackout periods.
