This isn't the original Braniff, but Braniff 2. It's what was formed after the original went belly up.
While the original flew to Europe, Asia, South America, BN2 started up in 21 cities serving 22 airports (IAD/DCA) and based itself in it's old home town of Dallas.
Later I'll post timetables from Braniff 3.
As you see they didn't have many flights as only two columns were needed for travel out of it's DFW hub, so you can just times by two to see there were not very large. Except for a DCA-IAD-DFW route, all other flights were to/from DFW.
BN2 joined up with United in Mileage Plus mileage program and teamed up with Emerald Air and Air Spirit to seven small cities via DFW.
