LH is currently phasing out the A310-300 slowly, the A300-600R will follow but no dates for retirement are said. The obvious probelm is that there is no real replacement currently offered. Airbus has here the better position I think, from what I hear a socalled A330-100, an A330-200 shrink, will be launched this year in Farnborough with LH being one of the potential launch customers together with SIA and HF.
The long-haul sector will be expanded with some more A340-300 they have on order. The 10 ordered A340-600 will replace the current B747-200 which will be phased out then. I´ve heard once that LH is looking on its options to replace the current B737-300 and -500, here the A32X is clearly the leading plane but I haven´t heard anything about that recently.
Lufthansa City Line has just recently introduced their first CRJ200, the first of 10 ordered. They have another 10 CRJ700 on order plus being the launch customer for the Fairchild 728JET with an order for 60 firm plus 60 options.
Lufthansa Cargo has by now introduced a big MD-11F fleet and has now started thinking about a B747-200F replacement but no word about which planes being considered. It should be the B744F and A3XX-100F.
