Im also having major problems with LX (Swiss Airlines) . I took a trip back in December and they never got credited. I sent in boarding cards and BMI credited them 14 days later. I also travelled on two LX flights last Thursday and still nothing on my statement online. I booked online and entered my BMI number into it and also gave it at check in. The number did appear on most of my boarding cards xxxxxxxxBD*G so it was in ok . I have three more trips with LX over the next 4 weeks so I will proberbly have to keep all the boarding cards again and mail or email them to BMI . Its a bit of a pain to be honest but at least I will still get my points.
