Both airlines blame each other, but operating airline customer service had assured us repeatedly before travel that the ticket was okay even though we couldn't do OLCI and even at airport check in they said they would sort it out... but then didn't.
I don't think DoT will get involved in helping us figure out which airline screwed up. And anyway, I don't think they will do anything if one or both of them screwed up ticketing.
