We're flying with the kids for the first time in the summer (August). Not having been abroad for a few years I was a bit shocked to find you can pay extra to pre book seats. I think it will be about £80 for the four of us (me, dh and dc 8 and 6) for us for both directions. Clearly I'd rather avoid stumping up for this - if we don't do it is it likely we won't be able to sit together? It's a short flight so I don't mind not sitting as a foursome but I think the dc are too young to sit without us. Any advice welcome,
