Reverse ticket
 

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

As far as the airlines are concerned, this should not be a problem. It has been done in the US for many years to minimize the cost effect of the "Saturday night stay" regulation on some airfares.

Not a problem.

One risk is if you do not get to Germany to start your GER-UK-GER ticket, both sectors would be cancelled.

Look carefully at the conditions of carriage of the airline you plan to use. I don't see how someone can state without qualification that what you plan to do repeatedly is OK.

With respect, I can't conceive of any reason why that would not be OK, especially if you buy the initial positioning segment on a different airline.

With a different airline, sure, but buying AAA-BBB-AAA RT and nesting within it lots of BBB-AAA-BBB RTs purchased at the same time would cause trouble with some FF programs, especially if the purpose was to avoid paying more because of minimum stay requirements.

OP stated that he would buy a single ticket AAA-BBB (single means one way) to start. There is no nesting.
