interesting scenario. Somewhat along the same lines what if you book an F AS award or for that matter an AS F partner award...lets say.... FAI-ANC-SEA-(insert destination here). You book and all are in F except FAI-ANC is **coach because you are on a combi. If there is an A/C swap and a 738 or 734 or something ends up on the route do you get to sit in F? Or is it a big song and dance like the OPs issue?
