Houston → Mexico City flights

Median fare is $96 — but the bottom quartile starts at $76

Key takeaways

• Median fare is $96, based on 30 daily snapshots of the cheapest cached fares on this route.
• The bottom quartile (p25) sits at $76 — meaning roughly one in four sampled days showed fares at or below that level.
• The spread is wide at 119%, running from a low of $48 to a high of $105, signaling this route is genuinely volatile and timing matters.
• The $48 floor is real but rare — it sits well below p25, so treat it as a ceiling-busting outlier rather than a reliable target.
• The p75 is $100, so fares above that threshold represent the pricier end; if you're seeing $100+, more patience or flexibility may pay off.

The full picture

Houston (IAH) to Mexico City (MEX) is a short, competitive corridor — and the data reflects that. The median cached fare across 30 daily snapshots came in at $96, with the interquartile range spanning $76 to $100. That relatively tight IQR suggests the "normal" experience for most travelers falls in a narrow band, but the overall spread of 119% — from $48 to $105 — tells you the ceiling and floor can diverge dramatically depending on when you look and how far out you're booking.

The $48 low is notable but should be treated with caution: it sits far below the p25 of $76, which means it surfaced in fewer than 25% of snapshots. Chasing that number as a baseline expectation is likely to leave you frustrated. A more realistic target is somewhere between $76 and $96. Fares on short-haul international routes like this one tend to soften when there's still meaningful advance time — generally the two-to-six-week window before departure — but they can also spike quickly once seat inventory tightens. Given the spread observed here, checking fares across several consecutive days rather than booking on impulse is a reasonable strategy.

No dominant carrier pattern was identifiable from this dataset, so carrier-specific booking tactics aren't warranted here. One honest caveat: 30 snapshots capture a moment in time and don't account for seasonal demand shifts, holiday surges (particularly around Mexican national holidays and U.S. school breaks), or fuel-driven repricing. The $96 median is a useful anchor, but treat fares above $100 as a signal to wait if your schedule allows — and anything near $76 as a prompt to book promptly.
