I took my Aces flights on 4-29. I had 2 separate segments and 2 separate boarding passes, one for BOG - UIO and one for UIO-LIM, both being flight # 521. All were received at the same time when I was checking-in in Bogota.
LP informed me today that only the flight BOG-UIO posted.

Also, my Avianca, Aeropostal, Copa and National flights have still not posted.
