In June, airlines improved on-time performance from 2015

WASHINGTON – Airlines were running on time more often in June than they did last summer and travellers seemed to be finding less to complain about.

But that was before this month’s computer outage at Delta led to more than 2,000 flight cancellations, widespread delays and travel nightmares.

The Transportation Department said Wednesday that 78 per cent of flights on major U.S. airlines arrived on time in June, up from 74.8 per cent in June 2015.

But the on-time rate slipped from May’s 83.4 per cent mark.

Hawaiian Airlines and Alaska Airlines had the best on-time ratings. American Airlines had the worst.

Travellers filed 1,078 complaints with the government about all U.S. airlines in June, down from 1,567 a year earlier.
