Subject: Bus/Train/Plane from Bilbao to Barcelona
Hi Graciela. I have done a random search at http://www.renfe.es. I have found two trains, as I told you, from Bilbao to Barcelona : - Miguel de Unamuno, leaving at 10:00 and arriving at 18:50, 5200 ptas - Pio Baroja, leaving at 22:45, arriving 09:05, 6500 couchette

About buses, check in http://www.alsa.es. There are four daily buses 06:30 - 14:15 10:30 - 17:30 15:45 - 22:45 23:00 - 06:00 The price is 5355 ptas for a single journey, and you can buy the tickets via Internet.

And now the planes. The best prices are found with http://www.europebyair.com

Another random search showed for the 28th of April, 150 dollars for two people flying with Air Europa (09:45 - 11:15). The price increased to 200 dollars if you were flying with Portugalia, but you would be leaving at 19:00, and arriving into Barcelona at 20:10 pm

I hope it helps you.
