You may not see why these are relevant, but as you can see they are.
Thus, the answer to your questions are:
1. Depending on where A-B and C are, this may or may not be a problem, logistical or otherwise.
2. Depending on what you mean by "partner airline" and which airlines they are, this may or may not be a problem, logistical or otherwise.
