Frontier Airlines EarlyReturns (Pre-Alignment) - Sacramento to Mexico?

Is it even possible to redeem 25,000 miles for a flight to Mexico from a city besides Denver?

For lots of the dates I have checked, Denver - Cancun has availability but Smf-den does not. Does anyone else have experience booking travel to Mexico from an airport other than Denver?

I would recommend calling, they seem to be able to look this stuff up a little faster than i can online. You might try checking SMF-DEN for availability as that appears to be your hangup. Perhaps you could fly out of SFO or San Jose instead if there is better availability. Good luck.
