To cut it short, I was on a TP run to MIA on a 125 ticket. On the return from MIA my flight to JFK went TECH so I lost the flight from JFK to LHR. I was rebooked on the direct flight on BA from MIA to LHR. I was originally in I class but was rebooked in J so more Avios. My TP year ends in beginning in july and I have calculated that I will reach excactly 1500TP before that, so I do not need the TP from MIA to JFK.

The question is, if I do an ORC on the AA flight from MIA to JFK, will they remove my posted flight and Avios from MIA to LHR and insert the JFK to LHR instead in I class? I will get more Avios by keeping the flight from MIA to LHR in J class. Or will I keep my J class flight and add the AA flight only?
