One small thing I might suggest. There's a convention some of us use for spelling out the routing, and that is to put stops in caps and transits in lower case. Thus AMM-lhr-SYD-nrt-DEL... rather than your AMM-xLHR-SYD-xNRT-DEL... Why do it this way? The reason is that tools such as the Mileage Monkey or the Great Circle Mapper don't care about the case, so one can just copy the string and paste it in without having to then delete all the 'x' notations (and even worse is when, as some people do, the airline code for each flight is also interspersed). The logic behind this method is simple: when asking for help, one should always try to make it as easy as possible for potential helpers.

cheers,
