A few years ago we had 2 little cherubs behind us that kicked the seats all the way from Montego bay to LGW !!
And a guy in front with a bawling baby on his lap-reclining his seat back, even after being told by the BA cabin crew three times to put his seat in the upright position!
Fortunately there was an empty seat next to me so I moved over so i could get a bit of room--thoughtless parents and unruly kids are a pain on flights---totally agree with Nivsy and Rainboe!
Never had the problem on flights to GIB Nivsy--normally golfers or Businessmen!!
