In an old OAG timetable I was checking connections between Cape Town and Munich. This was at the time when Lufthansa flew FRA-JNB-CPT on a B744 and MUC-JNB on an A343 (currently, they fly FRA-JNB and FRA-CPT on separate B744s). According to the old timetable, back then passengers wishing to fly on LH from CPT to Munich could fly the CPT-JNB leg on LH's 744 continuing to FRA, deplane in JNB, and then switch to the A343 heading to MUC.
Am I reading this correctly? And if so, under what arrangement is the intl carrier permitted to shuttle pax on a domestic leg in order to connect pax to another flight in its network?
I also have some vague recollection that pax who flew pre-9/11 on the then KE flight to LAX with a stopover in HNL were permitted a stopover in HNL and could continue on a different day to LAX on the same KE flight. This applied only to pax who had a through ticket SEL-LAX on KE and not pax first boarding in HNL.
Would be interested to hear your insights on this topic!
