OK explain details to me please. Again there were flights I often paid $1500+ in prior days to flight upgrading a $500-$600 one-way fare paid by company. Still $2000 one-way. My question is if revenue and margin is ultimate goal how much over $2000 can they get from SFO- BOS one way on any type of ticket? This is just example of many similar flights in 2023, some to smaller hubs.
