This was a month ago or so.
Even checking now SJO-SFO via copa
Tomorrow March 28, 2023 (28 hr) for $3,547 OW
March 29 2023 (10:36 hr) for $1868 OW
March 30 2023 (15:41 hr) for $2,184 OW

My point in the original post was the lack of mixed cabin ticketing on Copa causes difficulty in flying J to the USA if not originating in PTY. That lack of Business in AV, just makes the situation worse.Additionally, the prices are currently insane, though to be fair it is in both classes of service and both Copa and AV.
