I am looking at flying from UK to GER on a Wednesday then return on the Thursday every week, it was very expensive doing it this way.

Is it ok to reverse my travel direction so:

Initially buy a single ticket for Wednesday week 1 UK to GER

then

Thursday week 1 GER to UK return Wednesday week 2
Thursday week 2 GER to UK return Wednesday week 3......

As I see it I am not nesting flights and I don't believe this is back to back booking either.

Come someone clarify this for me.
Cheers
