Doesn't seem to work for anytime other than BOG right now (though I can't say I tried many bookings).

It's not clear to me what the flight reference and passenger reference is (a single pax PNR to BOG had passengerRef=2).

I only have one flight departing YYZ (to SFO) in the next month and it didn't work there either.
