Do a dummy booking, then right down the bottom of the page is a little link – Mileage calculator – this takes you to another page where you can work out what you’d earn. A random date shows that the direct flight is a codeshare with BMI Regional earning from 125 miles in cheap economy, up to 2500 miles in expensive business class if you hold status with them. You need to take note of the booking class. The dates I had a quick look did however throw up 1250 miles each way on an economy fare.
I’ve found with Miles and More that it can be fairly hard to earn miles flying, unless it’s at short notice, or in business/first class, but stuff like hotels can generate a lot of miles if you can take advantage.
Edit – Like CFH points out with the 35000 miles to redeem on that route – often economy redemptions are poor value, and Miles and More are pretty bad for the taxes they make you pay as well – often this equates to the same as a cash fare.
