I had checked on DEN MCO in early June a couple of months ago. There was availability. I then checked a couple of weeks ago and there was no availability.

This is one of the huge advantages of Southwest and the no change fee policies. If I would have had RR awards, I could have booked it and locked myself in on WN, knowing I could cancel later if the trip didn't come together. With F9, I can't do that, so I have to either wait (and the availability disappears) or I have to risk $75 per ticket.

I use my RR awards so fast, because they are so easy to use. I've got balances with the legacies because they are not as easy to use. Then the balances get depreciated as the legacy carriers change the rules.

Give me no change fees any day.
