I have flown often with ONEWORLD airlines and I've always registered either on-line or at check-in my membership with Iberia. I've found a bitter surprise have seen that NO miles from British Airways, Japan Airlines and other airlines used were added to my mileage. I've ask to the airlines I've flown with and they've given the fault to Iberia never proofing their transmission to Iberia. Result: thousands and thousands miles lost. Did anybody experience such a problem? Could anybody help me on how to act to get my mileage back? Thanks in advance!!
