When I was a teenager my friend Mickey and I did all kinds of things together. Ozark Airlines had a weekend special where you could fly anywhere Ozark flew over the weekend for either $30 to $40 (I can’t remember now). You could fly all weekend if you wanted to and that’s just what we wanted to do. Ozark was a regional airline so it just covered the midwest and upper midwest part of the US.
We got hold of their schedule and planned an itinerary that took us to 15 cities in two days. They were mostly small towns in Missouri, Illinois, Oklahoma, Iowa and Minnesota. We spent the Saturday night at a hotel near the airport in Minneapolis.
I still remember walking onto the airport tarmac and up the steps into a plane like the one on the right (click to enlarge). Because of the tilt in the aisle you had to sort of climb your way up the aisle to your seat.
Ozark went away when it was bought out by TWA in 1986.
Here’s a segment on Ozark Airlines that features a short clip of George Carlin doing a commercial for Ozark.
