HI
In the AA timetable, I've found flights AA 6290 and 6291 for LHR-AMM and AMM-LHR.
I'd like to put them to my LONEx, as this flight would earn 0 miles on RJ carrier.
However the online tool ignores AA, and when I check availability on EF, there is absolutely nothing for AA 6290/1 in any booking class.

Does this flight exist in any direction?
