Vueling allowance at a glance
| Option | Bag | Maximum size | Weight |
|---|---|---|---|
| Free allowance | Underseat bag | 40 × 30 × 20 cm | No separate maximum stated in the cited summary |
| 2 pieces on board | Additional overhead bag | 55 × 40 × 20 cm | 10 kg |
Quick answer: a packed 40 × 30 × 20 cm bag fits the free stated size. A second overhead piece needs the relevant service, fare or qualifying seat.
Underseat versus overhead
The free piece must fit under the seat in front. The larger overhead allowance is a separate entitlement and should not be inferred merely because the bag itself fits 55 × 40 × 20 cm.
Check the operating carrier
For codeshares or connecting itineraries, rules can differ by segment. Use the operating airline shown on the ticket and check each segment separately.
