WASHINGTON—More flights on US airlines are running late or getting canceled, and complaints are rising. The Transportation Department said yesterday that 76.9 per cent of flights arrived on time in May, down from 79.6 per cent in April and 79.4 per cent in May 2013. Hawaiian Airlines and Alaska Airlines, which get good weather on many routes, rank best. ExpressJet and Envoy, which fly smaller planes for big airlines, rank last.
The government says the largest airlines canceled 1.9 per cent of their US flights in May, nearly double the rate in April and last May. Four domestic flights—all on United —and one international flight were stuck on the ground longer than federal rules allow. Fliers filed 1,010 complaints with the government against US airlines, up from 720 a year earlier.
