I'm just spitballing but... F9 probably still made money through it all.

I'm told that we rarely offer refunds - just seats on the next flight when one cancels and some voucher or something. And, since it's the holidays, most people aren't too pressed for time and accept. As much as I'm sure JPATFO (that's, JP and the Front Office) aren't overjoyed at what happened, I doubt they're very seriously worried. It's not like EVERY airline at DIA didn't have problems.

When weather rolls in, airlines get a pass for the most part - despite how badly it is handled.

About the only really concerning issue is that ground service remains an issue that needs to be addressed for customer satisifaction reasons. I'm sure that contract is so cheap, there are many people in those meetings who shrug off whatever shortcomings are felt.
