Just added:
YF76 -- RT F North America-Asia (Post Feb. 2014 travel)
YF52 -- RT F North America-Europe (Post Feb. 2014 travel)
YB52 -- RT J North America-Europe (Post Feb. 2014 travel)
UP52P -- OW Upgrade P-ON North America-Europe (Pre Feb. 2014 travel)
I'm not sure the coding is going to be any different for pre vs. post Feb 2014 travel.
