I am travelling back to my country from Venice, Italy next month, and I have a 8 hour lay over from 11h to 19h at El Prat airport in Barcelona, Spain.
My First question : Do the airline company automatically transfer my luggage the next flight (since is the same company) Or do I have to grab my luggage and go again through customs and airport-security? if so, is there any luggage storage available?
My Second question : if the airline company automatically transfer my luggage the next flight (hopefully) is it possible to go outside the airport and what are the tourist attractions that I can visit during the 8 hour window?
I did some research and i found that there is three affordable options : Aérobus, public Bus, and the train, but it's my first time in Barcelona and I don't have a good estimate on the transportation time.
I have to mention also that the flight is assured by the same Company (Vueling) and I do have multi-entry Schengen visa.
