Flight numbers on LH pdf online timetable are indicated as either
1. operated by LH
2. operated by DE
3. operated by partner (direct)
4. operated by partner (change aircraft)
Those operated by partner airline (indicated by black diamond icon) can either be Lufthansa Regional (which carries only LH numbers) and other codeshare partners (Star Alliance or otherwise).
For comparison, BA & UA pdf schedules clearly indicate the flight number assignment e.g. BAxxxx is operated by GB Airways (BA franchise) or Aer Lingus (codeshare) or UAxxxx is operated by Air Wisconsin (UA Express) or US Airways (codeshare).
Can anyone provide me with a list of flight number system used by Lufthansa? I'd like to know as to which flight is operated by Lufthansa Regional and which one is codeshared - there's no way of telling this as they are both grouped together as 'partners'.
Thanks in advance!
