Thanks CWS we checked daughter in at T-23.58 ie just after Me wife and elder daughter, none of us had paid to book a seat as lowly blues it would add £600 to the trip both daughters now bronzes (if BA credit 140TP despite the downgrade). We did keep trying to check daughter in through the the day. Perhaps I need a far east mileage run early in my next year before the next family avios holiday to prevent same next year.
