Swiss will phase out their last MD-11 (HB-IWE) at the end of the summer timetable (It’s due to operate the ZRH-EWR route until then). The ones that LX have recently retired (with the arrival of the A340’s) have I believe mostly gone to Varig (and Varig’s have gone to LH for Cargo conversion… This is because the LX ones had PW engines, and LH Cargo’s were GE engined, as were RG’s. As LH have more clout within Star, LH managed to rig it so they kept engine commonality.)
