ITA booking code function error
 

Does anyone know if the ITA booking code function has been disabled?

I have been searching for a fare in a certain fare code, and typically will search like so:

XXX::DL+ /bc=M

when I do that now, I get an error page saying this:

No Trips Found

Illegal command-line prefix:bc=M

This is on a month long search.

Any input would be helpful...

try it like this:

XXX:: DL+ /f bc=M

Thanks! It worked. Not sure how I was getting it to work for the last year...
