Spanish low-cost carrier Vueling’s new Duo seat guarantees that you will travel with nobody in the seat next to you. The window or aisle seats in row 1 also give extra legroom and there’s a dedicated check-in desk in Madrid and Barcelona. You get preferential boarding whenever you want and are the first to disembark, free inflight drink and snack, and guaranteed hand luggage space. Duo costs €60 on domestic flights and €70 on international flights.
