transparent
As
WineCountryUA indicates, you used the term "back-to-back"
To airlines, that means buying several tickets, often in the same markets, in an attempt to get around the 3 night or weekend stay requirements.

It sounds like you were buying consecutive tickets vs back to back, but to clarify... did ANY of your ticket "overlap"?
