Best Time to Book

Dallas → Chicago flights

Median DFW–Chicago fare is $98; the middle 50% of fares cluster tightly between $98-$101, so book whenever convenient.

DFW–Chicago hovers near $98 — outliers drive the real swings

Key takeaways

Median fare sits at $98, with the bulk of observed prices (p25-p75) packed into a narrow $98-$101 band
Headline spread looks wide at 70%, but that's driven by a handful of outliers — low of $80 and high of $136
With fares that tightly clustered around the median, there's little evidence of a dramatic 'sweet spot' day to target
Only 12 snapshots were sampled, so treat the $80 low and $136 high as edge cases rather than reliable targets
If you see something near or below the $98 median, it's a reasonable price — no need to hold out for a rare dip

The full picture

The DFW–Chicago route shows a median fare of $98, and the interquartile range ($98-$101) tells the more useful story: most of the fares we tracked were extremely close to that median. The 70% spread figure looks dramatic, but it's almost entirely a function of two outliers — an $80 low and a $136 high — rather than a route that regularly swings wide. In practice, this is a fairly stable, low-cost corridor.

Because the bulk of fares cluster so tightly, we don't see strong evidence of a booking window where prices reliably soften. Unlike routes with genuine seasonal or advance-purchase volatility, this data doesn't support waiting for a dip — the $98-$101 band appears to be the going rate most of the time, and the $80 fare looks like a rare anomaly rather than a repeatable pattern. If your travel dates are flexible, you're more likely to encounter a fare close to the median than one near either extreme.

We don't have visibility into a dominant carrier or day-of-week patterns in this dataset, so we can't make claims about specific airlines or weekday departures being cheaper. The honest takeaway: this is a short, competitively priced route where $98-$101 is a fair price to book at, and chasing a lower number may mean waiting on a low-probability outlier. One caveat worth flagging — with only 12 snapshots, this sample is thin, and the true range of fares over a full booking cycle could be wider than what we've captured here.
