I'm trying to firm up a route. I understand surface segments are now included, but using open-date segments may be used by specifying LON rather than wasting a segment on LHR-LGW. (I may be wrong on this though.)

Anyway, I've put this route to my TA:

wlg-syd-jfk-mia-sfo-dfw-sea-dfw-lax-lon-krk-lon-nrt-hkg-nrt-syd-wlg

The TA comes back with 2 problems:

1. I've 2 too many segments as LAX flies into LHR and KRK goes from LGW. Can I put LON if I say LAX-LON-KRK-LON are open-dated?
2. Can I have SYD appearing twice? I only want one stopover from that, the other is a transit.

Mileage Monkey is OK with it...?

Thanks.
