The vueling plane and flight were great. One thing to keep in mind especially if you are a girly girl and pack more than a backpack or buy a lot of souveniers....
We'd already been in Spain 10 days when we flew vueling from Barcelona to Madrid so by then my suitcase was too heavy and they do charge 6 euros per kilo over the weight limit of 20 kilos for a checked suitcase. This could add up really quickly especially if you're not expecting it....
Just wanted to let ya'll know.
