Was going to make this a different thread, but it might fit here too -- Is there any rhyme/reason to which flights are arriving leaving from T2 vs T4?

Early in the T4 days, Delta tried to keep certain destinations at T4, and even had signage to that affect. Is there any consistency to what's ending up where now?

I'm assuming all the 50 and 70-seaters will still end up at the bus-station at T2, but there's still 8 mainline gates at T2.
