Finnair, a large European airline, have a very poor boarding practice whereby they collect every passenger waiting at the gate into an even smaller closed in area after checking passports (again) and boarding cards - then simply open the boarding causing a crowd crush as ALL passengers attempt to board all at once. Surely a more controllable method these days is to board via seat row numbers?
