Thanks Avion. I thought I had seen the ORD-ZRH service as operated
with an A330.
I don't think AA will use a 777 from DFW, although given the fact that
American has close to 800 flights a day at DFW, it is possible if they
get code-share permission for many more flights for SR to list. AA's
777's are intended from LHR, possibly CDG, Tokyo, and a number of
Latin America destinations such as Santiago, Buenos Aires, Sao Paolo,
and other cities served with the MD11, which is being phased out.
Then again, American has so many 777's on order, it's quite possible
that DFW to ZRH might get one. Would be cool.
