Nothing new really. Last I heard may 15 class with 4 in it and one class a month after that with 4 in it.
Chatter about UAL recall in fall but nothing more than chatter except latest SSC report did lend some credence to the rumor.
Some PI rumbling out at IAH recently about increased class sizes beyond 4 but nothing more than that and no confirmation from anybody in the know, which the way airlines run is probably about 5 people and even they aren't sure.
