I just booked in November an ORY - MAD - ALC - PMI - IBZ and IBZ - PMI - BCN - MAD - ORY with Air Europa, one saturday night stay, for 240€ (and 8 segments). That's fairly cheap I would say
And if you are not based in Paris, you can easily add 2 segments to reach ORY (but I would leave some margin since that will have to be on 2 different PNR).
