Alaska Airlines First Class BOS to SEA
I'm not really a big fan of Alaska Airlines. They're product is serviceable and their service is adequate. However, if you have a pet, there's one big reason to fly Alaska Airlines: they're one of the few (if not only) domestic carriers that has a first class cabin that accepts pets. Ironically, it's probably because airlines with newer planes no longer have the clearance under their first class seating to safely accommodate pets due to more electronics taking space. Alaska Airlines, at the time of this writing, flies older planes on this route (that's my first class seat at maximum recline!) so they don't have that problem.
