These students made the most of their luggage allowances - they had dozens of boxes stacked up at the check-in counter. The young passengers were travelling on a Japan Airlines flight at Haneda Airport in Tokyo on April 2, 2019. There were many hard plastic tubs and cardboard boxes all laid out at the ground as the pupils made last minute adjustments to their luggage bound for the plane's cargo hold.Airport staff were seen frantically covering the cardboard boxes in sellotape to protect them during the flight. The filmer said: ''I was worrying about whether my suitcase was a fraction overweight. These guys didn't have that concern. There bags must have weighed a ton and taken up most of the hold.''
