i, m travelling from barcelona to seville on 26th august. which is the cheapest way to get? i knew about renfe.com , but i cant buy tickets in advance-it costs 73 eur. i alsaw visited vuoling.es but I do not know Spanish that well, a bit confusing and adds to the cost of baggage fees, insurance fees and the total amount is 90 Euros air ticket. I am confused, I have very little time to make a decision, which would be better and cheap?
