I'd just have reservations about landing on the reservation without a reservation if you know what I mean.
Remember when making a comfort stop that these places usually don't have electricity in the restrooms. It's pretty rare these days for anyone to wire a head for a reservation....
Electricity, hell you’re lucky if an airport on the Rez has a bathroom. There are plenty of airports on reservations. They get a lot os use from med flight companies. Landed at P10 last month when I needed to stretch my legs.
Off the top of my head, there's E24 at Whiteriver AZ, walking distance from the site of Fort Apache; P13, San Carlos Apache, near Globe AZ, where you can land and walk across the highway to the Apache Gold casino; also Tuba City, Kayenta, and certainly several others.
Maybe @Zeldman is the best to answer this, but are there airports on reservations like in Arizona and New Mexico? I really don’t see any on the charts. Maybe they are uncharted or what? I don’t know anything about reservation life so please forgive my ignorance.
