I believe this has been discussed a couple of times on this forum - LX DOES NOT use Ama - they use an EDS (now part of HP) system (more or less the same system, that has been used by Swissair). If there is no LH/LO/OS/JP/OU/TG/JK/JJ/BD/SK-operated segment in the itinerary, THERE WILL BE NO AMADEUS RECORD LOCATOR created.
