Hi Jason,
I have been looking at the Pearson website and it is only showing FJM141 MKJP-CYYZ arriving late at 0910 local and departing as FJM140, maybe they have the wrong details in the aircraft FMS.
As for the UAL501 this shows one of the problems I have with United flights. For most of the week it operates KBOS-KOPRD but it is also used to operates KORD-KSAN and KRSW-KEWR on two different days each week. This is the reason most UAL flights are left without route info
