Frontier Airlines EarlyReturns - Is Frontier Still Flying DEN - SAT?

If this has been discussed and I missed it, I apologize.

I tried to book DEN - SAT tonight for a couple upcoming biz trips in late May and early June, and regardless of the dates I enter, I keep getting the following error message, "No flights found according to your search criteria. Please try again.".

Has F9 cancelled this route?

It appears May 16 is the last day of service available. This is the same message that came up for TPA service, but with a mid-August service cut-off.

Are changes in the works? If SAT is indeed being suspended/abandoned, 2-1/2 weeks is not much notice!

It has been missing for a while-

Thanks for the help. Knope's message didn't come up in my FT search. SAT is definitely discontinued as of May 17. Figures!

I'm curious why this route is being discontinued.

The January T100's recently posted in another thread show an 88.1% load factor - among Frontier's highest in January. I'm guessing the fare competition from UA and WN must be absolutely brutal to give up a market with such high loads.
