SEs do not have to pay for seat assignments, even on Basic Economy tickets.
I'd be curious to know the fare basis for the return.
I had a suspicion, but the published UA fares I see look like "KNA5A2EL", which I would have assumed AC would infer as Business Lowest.
The Fare basis for YLW-YVR is LT2HZATG
There must have been some odd fare rules with the itinerary because I ended up booking a separate SFO-TPA leg. It was close to $4kUSD to have them all on the same ticket or about $2400USD to book as different tickets.
