It was a Vueling flight. Boarding was super quick and organised. Didn't eat or purchase anything so cant comment on food. It was a short flight so there was also no entertainment. Disembarking was done in rows which I though was a good idea however people continued to make it seem like a really challenging task. Trying to walk back for bags, waking from seats further back when it wasnt their turn etc.
