I am simply interested in booking a flight in one of the fare classes that appear for my search.

In this case, it’s YUL to LYS on May 21.

I see a flight with AY at $202 in booking class O. I see 4 O seats available under the Availability section, and I’ve also read the Fare Rules and the Routing Rules, and everything looks good. But when I plug the numbers into ITA (using your handy “Find Flights Using This Fare” function) it consistently gives me “No flights found.”

I tried it for another class (K) on LH just for fun and I got the same thing.

What am I doing wrong?
