Thank you very much for that, heidelberg- a bit steep for the family of three though, might just confine myself to the home leg!!! Its really to get the extra leg room as my child is seasoned enough to work his way through his DVDs and nintendo DS quite happily on a long haul. One thought does occur, if a flight is full- mine are around Easter and seem to be filling up fast- are some pax placed in these seats anyway, without paying this supplement?
