Has anyone had any luck in getting seat preassignments done (whether in regular Y or MCE), or should I just start expecting to find myself in a middle seat next to the toilet in the last row on the codeshare segment?
I fly sometimes HEL-JFK-SEA/SFO-JFK-HEL, usually with AY flight numbers booked on AY web. Typically AA auto-assigns me one of their "preferred seats" at booking and I need the AA Record Locator to manage booking on aa.com. I can't recall having issues choosing a MCE seat for these bookings.
