The airline i work for, the Captian gives the F/As 15 mins to land! thats enought ime to secure the cabin etc, so we probably take our seat with 5 mins to land, if 7 men stood up for the toilet, and each took approx 4 mins in the toilet each, thats 28mins, it doesnt make sence, as there would still be people waiting for the toilet as the nervous family hurried up the jet bridge. a little far fetched one might say!
