Lufthansa Senator is not really equivalent to Super Elite.

It's more like something between 50K and 75K.

The highest LH status is HON, and that needs 600K miles in Business or First over two years. Benefits are great, except for for some reason baggage, which Lufthansa just... I don't know.

LH SEN is comparatively hard to get *G status. Granted we don't get spend requirements in Europe, but programs like TP, TK or A3 have half or even third requirements of mileage per year than SEN. In fact you can requalify for as little as 12k miles with A3, if you have 4 segments with A3 or OA (which means a single trip for a weekend on a Greek island).
The only disadvantage is, if you fly LH group a lot, there is too much 0 earning classes for these programs. Even discount business class earns 0 from LH!
