I don't know where you guys are getting your information.
New reserve rules are not in effect, except release to pairing after its assigned.
CAL had and still has long AND short call.
Most of the time (short or long) your trips are assigned at 1500 the day before.
The 737 is less commutable by far.
The new reserve rules are not much of an improvement. We are not using them, so we will wait and see.
