Sorry to piggyback on this thread, but my question is one of downgrading in case of overbooking. I booked QR MIA-BKK-MIA in business class for March. Remaining business class seats on the MIA-DOH flight are all blocked as are those on the BKK-DOH flight. There are a lot of blocked seats in both cases. I have seat assignments DOH-BKK and DOH-MIA, no problem there.

My question is what if there are no seat assignments when I check in? I don't know how often QR overbooks their flights and I fear a downgrade if that's the case. Does anyone have any experience with this?

Additionally, I set two alerts on Expert flyer for the flights in question in the hopes that program works (it's failed me in the past).
