My final destination is Texas to Barcelona. I've yet to purchase my plane ticket but I'm looking into flying out mid June and return in August. The volcanic ash cloud is keeping me from making a sound decision because I wanted to fly into London first since it is a few hundred dollars less expensive and I've never visited it so that seemed like a good possibility since I would be comfortable with taking trains to Barcelona. Flying to Barcelona, I believe is less of a risk with the ash cloud and I wouldn't be risking delays or cancellations. Any suggestions for this situation? Much appreciated!
