HI KVS - Just started using today.
How is the RTW function used to validate a trip say against the Oneworld Explorer rules?

I see the list of fares that it brings up but maybe I'm missing something.
I was hoping that this tool would validate the availability of a chosen RTW itinery say IAH-LHR-SIN-SYD-IAH and show if on chosen dates such a trip is available on the Economy L booking class code rules.

Does it do anything like this or do I need to check each leg separately. If it does not, is there a tool that does such? The oneworld website will validate a route, but will not check flight availability let alone booking class for you.
