American Aviation is one of the Page-based operators offering scenic flights over the canyon country around Lake Powell. The reason to consider it is simple: from the air, the lake, mesas, cliffs, and carved side canyons make geographic sense in a way they rarely do from the road.
This is a weather-dependent splurge, not an essential stop, and you should compare current routes, aircraft, and cancellation terms before booking. It belongs in the guide because Page is a flightseeing town as much as a gateway to Antelope Canyon and Horseshoe Bend.
