220 seats: 12 good, 16 mixed, 6 to avoid

Rows 11 and 26, seats A, B, C, D, E and F (Economy): exit row on Iberia's plan, with open floor in front at the door: lots of legroom, though people pass through to the door and lavatories.

Row 38, seats A, B, C, D, E and F (Economy): last row of Economy, with lavatories and galleys drawn right behind it: expect queues and galley noise.

220 seats: 30 good, 10 mixed, 12 to avoid

Row 1, seats A, C, D and F (Space One): space One, the front row: about 20% more room than a standard seat by Vueling's figures, nobody in front and first off the plane. The front lavatory and galley are just ahead.
Rows 2–4, seats A, C, D and F (Space Plus): space Plus: one of the extra-room rows 2 to 4 Vueling sells near the front, with priority boarding and a quick exit.

Row 12, seats A, C, D and F (Economy): exit row behind door 2: a lot of legroom; you must be able to help in an emergency.

Row 27, seats A, B, C, D, E and F (Economy): row in front of the door 3 exit: recline is likely limited.
Row 40, seats A, B, C, D, E and F (Economy): last row, against the two rear lavatories: likely limited recline and the queue beside you.
