We first told you about the sour summer travel forecast last month. Well, unfortunately for summer travelers, that forecast is being confirmed in this LATimes.com article. According to the article, this summer is becoming the worst for U.S. air travel with passenger complaints skyrocketing 43 percent due to late domestic flights. The Transportation Department blames severe storms and more planes in the air for the delays. Airports that were able to avoid the bad weather, like LAX in Los Angeles, actually moved up in the rankings since 81 percent of their planes departed on time between January and June. Only five other airports had an on-time record of at least 80 percent—all on the West Coast. Chicago's O'Hare International Airport led the way of airports dropping in rank with a 65 percent ranking for on-time departures, followed by the airports in Cincinnati and Washington D.C.

An airline industry consultant blames the delays not on the bad weather, but on an antiquated air traffic control system. No matter what the reason, if your remaining summer plans include traveling by plane, make sure to allow extra time on both sides of your flight so you don't miss important meetings or events.
