Dear ExpertFlyer,

I have a confirmed booking for a routing AAA-BBB-CCC / DDD-BBB-AAA with LX. Between each flight there are several days or even weeks (i.e. stopovers not layovers). I would like to move forward the flight DDD-BBB one day and the flight BBB-AAA one week back. How can I check the availability for a certain booking class either for rebooking or a new booking? I guess I can't search for single segments, as they are married segments? And LX doesn't offer the same fare classes for rebooking or a new booking. Thanks.
