Is there an auto process to MCS? Will one process at T-24 and one at T-12? (When traveling with someone w/no status, either the PNR needs to be split or you need to pay for both.) Also, will the system allow an upgrade to F at T-24 for both?

Overall, the upgrade system (and even sitting with a companion in MCE) is horrible when not traveling alone, the biggest downside of VX for me.
