Most matches into a new airline ask you to start from nothing; the move from Air Canada Elite 50K into 
Alaska Atmos doesn't. One match, open globally, carries your Elite 50K status straight to Atmos Gold — no fee, nothing to earn first, just the match request itself.
From Atmos Gold, one branch continues into JetBlue Mosaic 1 and on to Southwest A-List; both of those legs are scoped to the US market, and the reference below walks through the exact terms of each. That covers the airline side of the chain — Atmos Gold is the free foundation everything else builds from.
A separate branch off Atmos Gold runs through United 
Premier Gold, matched globally, and 
National Emerald Club Executive Elite, open to CA and US members, before the car rental matches begin. From National, one path goes straight to 
Sixt Platinum, a status that doesn't expire once granted. The other continues to 
Hertz President's Circle and forks again into 
Avis President's Club and 
Enterprise Plus Platinum — car rental brands routinely match off each other's status, so crossing from National into Hertz and then into rival Avis and Enterprise here is standard, not an error. Every hop's exact terms, including what it takes to keep United's Premier Gold status once its initial period ends, sit in the reference below.
