Yeah I hope my flight is not cancelled, looks like anything going through or out of N. Europe might be cancelled.
closest subway station to Riviera I think is Puerta de Toledo, looks like walking distance... there is a subway at the airport, but looks like you have to make two transfers. look at map here

I dont know about tickets either, but Im just gonna assume showing the credit card or ID will work...
Yeah I saw that Barca-Espanyol is on Sat., now I just wish I could go to that, maybe there will be tickets outside before the match? probably will just watch on tv....
