All flights were on one carrier: American Airlines. AA's in an alliance with Iberian, Finnair and others. But I guess each one was selling the same flights, with the same rights and everything, at different prices, on one ticket.

But I do see Google's OTA listing offering things like you say where you're not protected in the event of a missed connection delay and have some shady insurer that's supposed to 'protect' you outside of the airlines.
