Guam to Honolulu

What the Data Says About GUM to HNL

The Guam to Honolulu corridor (GUM → HNL) covers roughly 3,801 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,023 flights in the dataset, this route posts a 90.9% on-time rate with an average delay of 100.5 minutes when flights run late. Over the most recent 24 months of BTS data, 735 flights were recorded on this pairing — 8 cancelled (1.1%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,023 total flights analyzed, the 90.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 100.5-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Monthly performance varies, so review the monthly table above to see specific periods. For travelers evaluating the GUM to HNL route, the combination of a 90.9% on-time rate, 100.5-minute average delay, 1.1% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
