I have always got frequent flier miles on airmiles tickets. You need to check the ticket terms prior to booking. I have noticed over the last year that itins that are all Lufthansa operated flights usually state that the ticket will not earn miles, but if the first leg is operated by AC the terms do not state this.

2 years ago we did YVR-YYZ-FRA-AGP/BCN-FRA-YVR first leg on AC rest on LH and got ff miles TK for me and split AC and UA for my wife. We will be flying to Turkey this spring, originally with AC first leg to FRA, and rest on LH, but due to schedule changes are now on all LH plus one TK leg from IST to Izmir due to LH no longer flying to Izmir, so will be interesting to see if we still get our ff Miles.
