Sit on the Right side of the plane for the best views on flights from Pittsburgh (pennsylva) to Denver. The right side misses the Pittsburgh departure view but delivers the dominant visual payoff of the flight: the Rocky Mountain Front Range on approach into Denver is one of the most dramatic arrival views in domestic US aviation. The left side wins at departure but the mountains on landing outweigh that advantage for the overall experience.

During takeoff from Pittsburgh International (PIT), sit on the Left side for the best views. PIT typically departs westbound on runway 28C/28R, then turns northwest before banking west-southwest toward Denver. A left seat gives you the view back over Pittsburgh's downtown Golden Triangle where the Allegheny and Monongahela rivers meet the Ohio, which is one of the most distinctive urban river confluences in the country. You'll also see the Monongahela valley stretching southeast. Notable sights include: Pittsburgh Golden Triangle (three-river confluence), Monongahela River valley, Ohio River bending northwest, Allegheny River corridor.

When landing at Denver International (DEN), sit on the Right side for the best views. DEN typically lands eastbound on runways 34R, 35L, or 08, depending on wind. On the common westerly approach, aircraft come in from the east or northeast, and the right side faces south toward the Front Range — you get a clear broadside view of the Rocky Mountain Front Range including Pikes Peak to the south and the Denver metro spread across the plains below. The left side faces north toward open plains with less visual interest. Notable sights include: Rocky Mountain Front Range, Pikes Peak (distant south), Denver metro grid on the plains, Chatfield Reservoir.

The flight from Pittsburgh International (PIT) to Denver International (DEN) takes Approximately 3 hours 15 minutes.

The flight crosses the Ohio River valley, then the flat agricultural plains of Indiana and Illinois, the Mississippi River near the Iowa-Illinois border, the Missouri River, then the increasingly arid high plains of Kansas and eastern Colorado before the Front Range rises dramatically on the western horizon roughly 45-60 minutes before landing.
