Hoping someone might be able to answer this Q as not been able to get in touch with Vueling directly.
We're flying with them on 3rd August and just went online to book our seats - to find they've already allocated us some together. Does anyone know if this is likely to change? We were expecting to have to pay to pre-book seats together (travelling with young kids) but if the seats have been allocated and won't change, we don't want to waste the money.
