Old Gold, don't forget America Wurst and NW FF programs are partnered. What if it is two airlines that don't have that arrangement?

I lived in Tucson in the mid-90's. We went on a great trip TUS-LAX-CRN-BRN-SYD-AUK-LAX-TUS. The "travel agent" booked us on HP for the LAX-TUS return because he said the DL flights were sold out. Turns out the flight we were booked on did not operate on Saturdays. We ended up getting on the DL flight anyway and the agency paid the fare diff, but HP was anything but understanding or accommodating and once we topped off our miles and used our freebies to go to Cabo, we avoided HP at almost any cost. If we did have to fly HP, we took the CO miles.

Like I said in a different thread, if anyone with any class and any cash would buy America Wurst and turn it into part of a real airline, what an asset that would be!
