I've come to my personal conclusion that both IB and AY are very slow in crediting flights to other airlines' FF programmes. Conincidentally, both airlines use the Amadeus Computer Reservations System.

BA seems to be one of the fastest (next day or maximum 2 days later) to credit CP and AA's FF.

CX takes about a week in average.

QF takes less than a week for AA's FF but between 2-3weeks for CP and CX's programme.

Happy holidays everyone...did we complete our OneWorld challenge?
