Operating a fleet within a fleet wouldn't be too much of a problem - we ran the -200's that way for a few years. My guess would be that we (if this were to happen) equip the whole fleet to keep things standardized.
Yea, we still have the AT's and the VNAV disabled. The VNAV "info" is there on the PFD, you just have to manually start down at the top of descent. No big deal really, but AT's would be nice on the long hauls.
Do any of you guys know if places like Puerto Rico and the rest of the Caribbean can effectively be run without rafts? We have added the vests, so were good out to 162nm from shore, but I don't know if that's enough.
