The DC fly and have flown without us at least half a dozen times in their poor neglected upbringing
. Twice long haul with their GP's. They were delighted when GP's got an upgrade and left them in peace on the return journey with their playstations, i-pods sweets.They were 13 and 14 at the time and were mortified by granny constantly coming back to check on them.
Poor granny was torn and quite distressed, grandad had a ball and got pissed.
I have never thought that sitting apart from my DC on a plane as a problem before.
On our last holiday I saw my DC for half an hour in the morning, an hour at dinner and briefly as they slunk in after midnight. It was the best holiday DH, DC and I have ever had.
