As I’m coincidentally trying to get to Riga for a conference, I looked in to this, and the flights Google comes up with (last leg LHR > RIX) on Baltic Air won’t come up with AA, even putting in the segments individually. All flights route to Helsinki, then end on Nordic Regional using an ATR 72.
I may call and try to get an agent to book it – but forcing that routing, it won’t likely price at ~500.
