This is a variation on the above thread.

Just checked in for the night flight to AMS tomorrow and got the "volunteers needed" prompt. I bid for $600 since it is an international flight and promptly told $400 was the limit. i was very surprised to get such a low offer. I went ahead and put in $400 because I have the time to wait and we will see what happens. There are other flights that afternoon but no non-stops, routing through DTW or LHR and getting in several hours later.

What are the odds of holding out for more than $400...and getting a FC seat on the transatlantic leg? Am currently in Economy Comfort. I've gotten $400 for domestic bumps, sure seems low for international travel.
