I'm a FB member and flew TLV-TXL-JFK-SFO-ATL-TLV on DL (TLV-TXL on LY). I forgot to give my FB card on check-in to the TXL-JFK flight, and these miles were not credited to my account. It turns out that I qualified for Silver elite level without the TXL-JFK flight, and when I mailed to the boarding pass to claim the missing miles, I got the 50% elite bonus for this flight, even though it was before I qualified.

Moreover, if I had credited these flights in order, I would not have received any bonus miles as I wouldn't have had the 25,000 EQM before I flew ATL-TLV.

Did this happed any one else here on FB?
