Just a comment for those using this tool ... aside from the fact it is great!
If you are using the ITN/UA interface to see fare classes it will show all the TANGO RINGPET classes ... the ITN/CWT interface does not show "R" or "T" classes ... something to keep in mind I guess...
This I suspect is the CWT back-end issue similar to it showing only a subset of Econony seating ...
