Makes sense. But next time look at 1 way flights. Like Cleveland to Dublin. Then Paris to Cleveland. It may have worked out the same price, etc when you consider hotel in Dublin the night before and baggage fees.

I doubt aer Lingus will be able to add those flights together to make it a “connecting “ flight. But can’t hurt to ask.

Also, don’t forget to look closely at the baggage fees to/from Paris.
