Yes. This type of stuff clearly violates airline contracts, but I'm curious about which laws are transgressed. We've discussed this extensively wrt hidden cities in isolation, but this is the first thread I've seen mentioning a switcheroo at the connecting point. I couldn't imagine tempting these waters myself, but I'm not familiar enough with relevant legislation to declare the OP's plan illegal.
