Forgot to add, that one of the biggest problems with the changes (IMO) is the changed timing for LH690 FRA-TLV, to 1930 I think. It is no longer possible to have a full work day outside FRA and connect to overnight flight on Thursday. I used to do that a lot from OSL, HEL, ARN, MUC and many others (even LHR). The new timing makes that impossible, and I don't like returning on Friday in winter (have had some bad experiences). May need to return via LX, or fly on BA (which has some quite good connections to night return flight LHR-TLV).

The changes will also make me much more likely to book cheapest economy class if I do fly LH - previously I would normally spend a few hundred dollars extra to fly business class, no longer....may make renewing SEN a bit more tricky...
