Here are the nation’s most delayed flight routes

If you have a flight from Chicago, chances are you’re not getting to your destination on time.

Data from the Bureau of Transportation Statistics show that nine out of the 10 most delayed travel routes in 2014 involved the Windy City, The Wall Street Journal reported.

The absolute worst route to take to land on-time last year? A trip from O’Hare to Knoxville, Tenn., which had its passengers arrive late 44% of the time. The airlines responsible for those flights were American (AAL) and United (UAL). That compares with an average delay rate of 23.8% for all airline flights last year, the Journal said.

Per the article:

While the worst-performing flights have been tracked before, this is the first time BTS has processed all flights on a route over a full year, yielding a more useful guide to trouble spots for travelers. (The data was collected at the Journal’s request.)
