F9Animal is right - it is too early to tell.
If you'd asked about DEN
this far in advance of service, it might have looked as if the route would be a dog. In fact the reverse is true - it's been gangbusters out the gate.
So I'm wondering if your question is related to the other post about the high Frontier fares BTR
over the Christmas week.
The answer might (a) it's Christmas week. That same route is $350 round trip all up in November.
(b) that they have amazing bookings for that week. That seems unlikely - this far out.
(c) they are expecting high bookings for that week. It may be possible they have some evidence of this. But you can get AA
that week for $350 for that route, so that seems odd.
I think it is simply too far away. Give it a month or so. See what happens.
