Round trip flight Barcelona - Ibiza

Hey Guys! I need some suggestions for booking round trip flight to BCN - IBZ.
Going to Spain very soon end of June, has anyone booked a flight within Spain while there, 10 days in advance? Or should I book now while in Canada?
There are hourly flights from Barcelona to Ibiza, like cheap commuter flights, no problem to get on one even on the same day. Enjoy your stay on Ibiza!
Thanks for your advice. Unfortunately my husband didn’t want to leave our flight till the last min and booked with Vueling spending $495US. Highway robbery! ‍♀️
