UA328 route overview: DEN to HNL

UA328 distance and great-circle path

UA328 covers 5,408 km, or 3,360 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 255 routes we track, it ranks 159 by distance.

The plane leaves Denver heading west. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the DEN–HNL route appears on a tracker map.

Why UA328 block time differs from cruise time

The schedule allows 7.5 hours from gate to gate. That works out to about 721 km/h. A Boeing 777-200 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying west, this route pushes against the wind. The trip back east is usually shorter, even though the distance is the same. See how high-altitude winds behave in our guide to turbulence and jet streams.

What to know about UA328

  • Time change: you land 4 hours behind the time you left.
  • High airport at the start: DEN sits 5,434 ft up. Thin air means a longer takeoff run.
