What Frontier Miles unlocks

If you already hold Frontier Gold, you're one step from Alaska Atmos Gold. Frontier's tier lines up exactly with Alaska's own status-match chart, so the switch is immediate: complimentary for 90 days, extendable by earning 10,000 base points on Alaska or Hawaiian within that window. It's a US match, and it's good for one lifetime use.

From Alaska Gold the routes split. One branch matches you into JetBlue Mosaic 1, which then converts into Southwest A-List under Southwest's own terms - a 120-day complimentary period you extend with three round trips or 11,500 points, with registration open through the end of 2026. The other branch lands you in United Premier Gold worldwide, a match that needs an activating flight to kick in and, if you want it to run through January 2028, 10 Premier qualifying flights plus 3,400 Premier qualifying points inside that same window; enrollment for it closes before the end of 2026 as well.

United Premier Gold is also the doorway into car rental status: it converts into National Executive Elite in the US and Canada. National Executive Elite then splits three ways: direct matches take it into Avis President's Club and into Sixt Platinum, while the third path picks up Hertz President's Circle first before finishing at Enterprise Plus Platinum - a chain that swaps across rival rental brands on purpose, with every hop's exact terms mapped in the reference below. Avis and Sixt are the simpler stops if you just want a top rental tier without chasing a fourth match.
