Getting off the ground in August was something of challenge if you were traveling by commercial airline.
According to the Department of Transportation's (DOT) Air Travel Consumer Report, there were 15 tarmac delays of more than three hours on domestic flights and five delays of more than four hours on international flights.
DOT is investigating the delays.
The carriers posted an on-time arrival rate of 77.6% during the month, an improvement from the rate of 75.2% a month earlier, but worse than the year-ago rate of 80.3%.
Airlines report that they canceled 1.4% of their scheduled domestic flights in August, compared with 1.0% the year before and 1.9% in July.
Other areas covered by the report include chronically delayed flights and the causes of delays, and other flight problems including baggage, reservation and ticketing, refunds, customer service, disability and discrimination.
The complete report is available on the DOT website.
