Heres a little insight on the flifo:
(this is typical flifo that shows up for us in CO
the L1.37 means its Late 1 hour 37 minutes
correct me if Im wrong, but I believe the ")" means that ACARS updated flifo, as opposed to dispatch or operations, which would result in a * after the time.
and the last line is the page that CARS makes in the DRS
for reaccommodation for any passengers that need protection. From what Ive noticed, usually the page is totally randomly named, which is why it has CNL in there (for cancelled) Hopes this helps!
ps- CARS = Continental automated reaccommodation System
