What looks like a Brazilian website suggests actors for roles in a Green Lantern movie. As you may recall, the Green Lantern cast includes Tom Kalmaku, an Inuit airplane mechanic.
Elenco Ambrosia: Green Lantern
Comment: This image makes Tom Kalmaku look more Asian than Inuit. Even so, actor Jonathan Ke Quan doesn't look any more like Kalmaku than a randomly chosen young Asian man.
As usual, I'd say choose the most authentic actor possible. Go to Alaska or Canada and have an open casting call if you can't find any Inuit actors in the Lower 48.
Despite the Asian eyes, this is the kind of face I'd suggest for the Alaska Airlines logo. Given the Alaskan context and the strong Native features, I think most people would identify it as a young Inuit man. They wouldn't need a parka to make the connection.
