An observation, I suppose...

Heading to the airport early today, I tried to change my ticket online (full Y). The flight I was looking to change to (which had availability, including y-up according to flyaow/classamex...) didn't show up. I tried searching various ways then called the elite desk. They said it was full up front & had 6 seats in the back. Checked again - flight showed up as stated. This was just before the 3 hour mark. I'm guessing that the records are totally locked (including coach seats) while EUA is actually running, therefore preventing potential customers from seeing availability on the flight.
