Threads on another board contain quite a bit of discussion which appears to be coming from gate agent types. Seems U is short of co-pilots for the A-319 (and by extension the A-320). Because of the pending United thing, they apparently aren't hiring enough new pilots, so what's there is running out of time during the month, mainly because of weather delays. With almost 100 of these aircraft types in the system, we might want to be careful when booking.
