Random chance?
If you are on a Frontier flight that goes out on time despite bad weather, you're not likely upon arriving home to check if the United flight scheduled at the same time was delayed, and then post a congratulatory message onto the Frontier forum

Nor would you post on the Frontier forum "Hey, why did your flight get to leave" if you were on the delayed United flight. A couple of pieces of anecdotal evidence does not make for real data.
I looked up the On-Time data from the DOT for all flights from LGA to DEN for 2012: (
http://apps.bts.gov/xml/ontimesummar.../src/index.xml). It took quite a long time to load (lots of data I'm sure) but has a ton of statistics. In terms of % of flights delayed, cancelled, diverted, and the delay length, F9 comes out on top of UA on some measures, and UA on others. Neither appears to have a clear advantage, certainly nothing that would point to a vast conspiracy
I would encourage you to visit the site above and draw your own conclusions.
