Best and Worst Airlines for Flight Delays
No. 18 JetBlue
On-Time Performance: 72.0%
JetBlue may be a favorite among fliers for its service, but its performance in 2011 was appalling, with more than a quarter of its flights running late. This is a new low for the carrier. In 2010, it turned in a respectable 78.1 percent on-time rate and earned itself a place at No. 12 on our list.
