My 'journey from hell' was an overnighter from Vancouver to Glasgow. We (DH, DD1 & me) had been stuck in the departure lounge for what seemed like a lifetime as a string of half hour delays were announced. I'm a nervous flier, an addicted smoker and a bit claustrophobic, so being confined and not permitted to return to the designated smoking area was difficult but what made it unbearable was a party of around 20 youths from a well known, respected and exceedingly expensive School, who proceeded to have a game of football between the seating. Although various waiting passengers remonstrated with them (to no effect) there appeared to be no one in charge of them although we had our suspicions about 3 men and a women seated in a corner who appeared to be oblivious to the mayhem.
Eventually we boarded the plane and found ourselves in our little row of 3 with the footballers, in front, behind and to the side of us. As soon as we had taken off and seat belts could be removed, the football appeared and was kicked up and down the aisles and thrown over the passengers heads. By the time the cabin staff had confiscated the ball (and the other one which then appeared) I discovered to my dismay that my 'restless leg' had kicked in so I had to go walk about, forcing my way past the teenagers who were now kneeling in the aisles gambling loudly with cards. I found a quiet space at the back of the plane by the toilets where I could walk on the spot and was soon joined by my DD, who also suffers from restless leg. We had about 10 mins of respite until the tannoy ordered all passengers to return to their seats as we were about to experience turbulence. The stewardess, although sympathetic (her DM had RL) admitted that there was no turbulence - this was merely a ruse to confine the lads to their seats - but we would have to be seated and belted while the light was on. The young gentlemen, unperturbed, started to sing.
So six hours, DD & me, strapped in our seats with 4 legs ( and one arm ) flailing, not even allowed to go to the toilet. DH, in the window seat, slept throughout the night.
Long Haul? Never, ever again
