Airports Around Barcelona

[RPD]

I am leaving Ireland the day before my cruise leaves Barcelona and I need to fly in and out of Shannon (my return flight home is from there). RyanAir (the cheapest airline) only flys to Girona and Reus airports. How far are these airports from downtown/the port? Thanks.

Girona Airport (GRO) is 80 km north and has continous bus service to Barcelona centre (Estació del Nord). The bus ride is 1 hour long. Reus airport is 100 km south, near Tarragona, and is not so well conected to Barcelona centre.
