The distance DOH-OHS is 321 miles.

They nipped hat little trick in the bud!
Doha-origin tickets are limited to a 1,500km change from the booked destination. So that rather limits the use of a Doha Sohar ticket in this game. And given the way QR milks Doha-origin business-class passengers, these were never going to be very interesting tickets to start with.
And before you think of trying it, Sohar Doha wouldn't work - tickets with Doha as destination don't even enter the game, only allowing changes within the origin country. Switching from Sohar Doha to Salalah Doha isn't going to float many boats
