AvoidDelays.com makes it easy to plan flights based on statistics. The information comes from the National Air Traffic Controllers Association.

What's hot: The top lists: Most delayed departure airports, worst times to fly into those top 10 most delayed airports, the most delayed flights and more. You'll find airport-specific tips to avoid delays.

What's not: The lists are not real-time but compiled from months-old stats. When I looked up delays for Los Angeles International Airport at 4:30 p.m. one Friday, the site sent me to the FAA, which posted the real-time info in Greenwich Mean Time. I then had to convert to Pacific Daylight Time.
