Trying to see if this is something that can be done. Three people traveling ORD-HND in June/July. One reservation booked through Chase and the other AMEX. Travelers 1 and 2 AA Executive Platinum, was able to select seats in row 5. Third traveler AA Platinum, looks like row 5 is blocked, assuming it was unlocked for EXP members. Any way to link the reservations to move the third person into row 5 as well?
