Sacramento/Cabo Mexico $69 each way plus tax

If you live in, or live within a reasonable drive from, Sacramento, this is a fab fare, and  you'll only find it on Frontier's site (and not on any other fare search, comparison, prediction, or whatever site). It's only available for a selection of dates in July, August, September and October. We were able to find seats easily. With tax, you'll pay $239 RT. Purchase by July 31. See the details.
