Hi,
The return direct flight from SIN to ZRH was booked with Swiss Air economy saver.
Due to different date for the outbound flight from ZRH to SIN, I booked for my sister with Swiss Air economy saver as well under separate booking reference with OTA, Expedia. My sister had paid the same airfarevas mine for economy saver class and her flight was eligible for miles claim. That was my point to share that booking with OTA, OTA managed to get my sister eligible booking class and captured her Krisflyer number. She got her miles credited right after the return flight while i get nothing for direct booking with airline itself.

After digested and accepted the fact that no miles earned for the flight in May 2019, Krisflyer Customer Service (KF) sent me further email enquiry yesterday to request me to provide the boarding pass of my flight in April 2019 from SIN to ZRH under Swiss Air Business travel class. Oh My! How can KF expect the passenger to keep the old boarding pass to ease their job? Well, I am so disappointed with KF working ability! I hope KF is not finding excuse not to process the miles claim.

Regards.
