Key takeaways

• $91 is the median one-way fare across 30 daily snapshots — a reliable anchor for this short-haul route.
• The bottom quartile sits at $87 or below — that's the realistic floor most travelers can actually hit.
• The absolute low recorded was $68, but the top of the range reached $109, a $41 spread on a sub-$100 ticket.
• A spread of 60% is notably wide for a route with a $91 median, suggesting fare volatility that rewards monitoring.
• With p25–p75 compressed between $87 and $94, half of all observed fares fell in a tight $7 band — most shoppers will land near median.

The full picture

Houston to Mexico City is one of the busier short-haul international corridors in North America, and the pricing data reflects a route with genuine competition keeping fares anchored. The $91 median across 30 snapshots is a credible baseline, and the interquartile range — $87 to $94 — tells you that on most days, fares don't stray far from that center. That's actually good news for budget planning: you're unlikely to be blindsided by a sudden spike into the $150s on a routine travel week.

That said, a 60% spread (from $68 to $109) on a sub-$100 ticket is worth taking seriously. In percentage terms, the difference between catching a sale and booking at the high end amounts to roughly 60% more money out of pocket. The $68 floor suggests promotional or seat-sale fares do appear on this route — but they're not the norm. Practically speaking, booking 3–5 weeks out tends to be the window where competitive fares on high-frequency corridors like IAH–MEX are most accessible; very last-minute bookings (under a week out) risk the upper end of the range, while booking too far in advance (beyond 8–10 weeks) may mean missing mid-window promotions.

Day-of-week or carrier-specific patterns aren't directly visible in this dataset, so claims about "cheapest days to fly" would be speculation. What the data does support: set a target at or below $87 (the p25 threshold), use fare alerts rather than one-time searches, and treat anything under $80 as a strong signal to book immediately. One honest caveat: 30 snapshots capture a single rolling window and may not reflect peak holiday demand periods — if your travel falls around Semana Santa, Día de Muertos, or December holidays, budget toward the $109 end and adjust expectations accordingly.
