One Way Flights: IAD to DUB and CDG to JFK

Today on Aer Lingus:
June 2nd, One Way Flights, from Dulles IAD to Dublin DUB = $800 per person
June 7th, One Way Flights, from Dulles to Dublin = $800 per personJune 9th, One Way Flights, from Dulles to Dublin = $830 per person

Aer Lingus doesn't fly Paris back to Dulles, so we'd have to do Paris CDG to New York JFK. It also looks like its not a direct flight, that we'd fly Paris to Dublin to JFK.

Today on Aer Lingus:
June 16th, One Way Flights, from Paris CDG to JFK = $550 per person
June 21st, One Way Flights, from Paris CDG to JFK = $620 per person

So doing the One Way flights, this way it would cost about $1,350-$1,450 per person.

The other option is that a One Way flight from Paris to Dublin = $90.00 per person and takes 45 minutes, so we could buy Round Trip flights IAD to DUB and also a One Way from CDG to DUB for a total of $1,090-$1,140 per person.

Savings of $260-$310 per person.

How FUN is all this coordination?!
