Passenger boarding times are quicker on low-cost carriers compared to the conventional block loading method, according to a new report. Tests have shown that the row-by-row method favoured by airlines is two minutes slower that random boarding used by no-frills airlines, according to published results in the Journal of Air Transport Management. This is mainly due to people restricting aisles or having to move to allow others to sit down. The report’s author and scientist Jason Steffen said the time spent boarding an aircraft could be cut by 40% if airlines adopted a different method. He suggested that passengers with tickets for window seats should board first, followed by those in middle seats then finally aisle seats. An even more efficient method would see passengers board in the same pattern but in alternate rows i.e. 20A, 18A, 16A then 19A, 17A, 15A etc.
