The reason I ask is I tried this through MIA (ZRH-MIA-IAH-PDX) and it was no-go; invalid routing. I'll call and ask. I just can't stand the long hold times (30+ minutes). I have no status.

Once I called OnePass and they gave me the option of ringing me back when an agent is available but now they are just having me hold. Is there a way to have the call back option done automatically instead of listening to the terrible hold announcement over and over and over?

Also, what is the longest permitted layover on an international award ticket? Is 24 hours permitted and not counted as a Stopover?
