Im trying to get from RDU-ORD on 6/21 returning 6/24. BA.com shows no availability in any class so I called the reservation line which confirmed they had no availability. The catch is that I can see seats on AA.com Should BA be able to long sell those seats to me? Did I just have a bad agent or is BA inventory limited on AA? Its important because we are celebrating our 5 year wedding anniversary.
