When I read the topic title, I thought it might have to do with the following example, which I have considered, but have never actually done:
(1) Buy a RT ticket LAX-LHR.
(2) Buy a RT ticket LHR-BCN with same departure and return dates as flight above.
(3) Remove staples from all tickets and arrange the four coupons and staple back together to give the impression that the two tickets were purchased as one itinerary.</font>
Why would you do this? It's certainly not a violation of the airline's rules to buy a LAX-LHR and a LHR-BCN ticket: I have on several occasions bought my MCI-LHR tickets as MCI-ORD R/T and ORD-LHR R/T to get significantly lower fares. The airlines don't care.
(Granted, I've never tried to check a bag all the way through from MCI-LHR when doing this. Maybe that would be problematic...or maybe it wouldn't.)
