Hello!
I am looking to book a flight departing 12/31 and returning 1/5. The flight we need because of work obligations on 12/31 is Frontier 0803 departing at 6:20 PM then connecting in DEN on Frontier 0341 arriving in BZN at 11:11.

There is more flexibility on the 1/5 return - although we do need to get in before midnight (preferably well before) on 1/5 due to school & work obligations the next day. Could depart from BZN anytime that day.

I have watched the fares and they have crept up the last couple of weeks. However, it looks like there are quite a few seats left on the 12/31 leg. Kayak gives something like a 59% chance the fare will go down. Should I wait a few days? I would be okay with booking two one way trips if that might be the best way to go. And any carrier would be okay on the return. If I could get one close to Frontier's fare, I would probably prefer another carrier because of the carry-on fees on Frontier. Oddly, although Kayak, Orbitz, etc. show availability for the 1/5 return on Frontier, the Frontier website shows "Service between Bozeman, MT (BZN) and Memphis, TN (MEM) begins March 03, 2015." I am puzzled by that.

Thoughts & advice appreciated!! Thanks!!
