Departure window

When United runs best on this route

There are not enough flights in each departure window to split United's BFL to DEN record by time of day without the percentages moving on noise. The headline rate of 94.0% is the reliable figure here.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 845 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.

The return leg is a different operation and performs like one: it runs 53.0% on time across 102 flights, 41 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 41 points of difference.

One caution: this is a thin sample. 101 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking United on BFL to DEN

Put together: treat all of this as provisional. 101 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 94.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 100 completed flights over 12 months sit behind that.
