Online Flight booking

I'm trying to get to Barcelona for a old friend's stags weekend.

We left it too late to fly direct from Dublin so I have to look into flying to London then from London to Barcelona

To check London onward connections

The main Airports are

Barcelona (central), airport code BCN
Barcelona (Girona), airport code GRO
Barcelona (Salou, Reus), airport code REU

Dublin airport code is DUB
London Stansted airport code is STN
London Gatwick airport code is LGW

God this is a nightmare getting a relatively cheap booking.

Best option so far is Dublin --> Stansted then on to Girona outside
Barcelona and the same on the way back...
