I hope they'll fix this everywhere.<p>It's really annoying when they want me to change the seat <i>I paid a premium for</i> because some family wants to sit together and didn't bother paying for it.<p>Especially Vueling Airlines in Spain does this all the time and I don't use them anymore. Ryanair is just as cheap but they respect what you pay for.
Primarily a software story:<p>> The biggest impediment has been technology investment, to make assignable seats available when young children are on a reservation with adults or to program automatic seat assignments to populate together in that case.
