In December AA511 goes direct ANC-IAH via PHX and AA1716 goes direct IAH-BOS via PHL. Counts as one segment on OW RTW tickets unless they have changed the rules. The flight schedules change so often that there are lots of direct flights you would never suspect unless you check. Lots of time they are only in one direction between city pairs but can make for excellent SC , TP , and 12,000 mile AA bonus on a DONE ticket.
