The Rocky Mountain News also published an interview with Kevin Knight, United's senior vice president of planning. An excerpt:
What is United seeing in the domestic market?
Our bookings continue to look pretty good, but we're also seeing capacity increasing versus what we saw last year. That's putting pressure on yields, which is putting pressure on the revenue side. So we're responding to that with a little less capacity. It's pretty much across the board. I wouldn't necessarily say it's low-cost carriers or legacy carriers; it's pretty much industrywide.
