Central America - SJO transit

Flying YOW-YYZ-SJO on AC, connecting to SJO-BOG on AV.

1. At SJO will I need to clear immigration and go landside, or can I stay airside?
2. Not sure yet if AC can issue my AV BP. Is there an airside transit desk where I can obtain my AV BP for BOG? I will have carry-on only.

Thanks.

I can now answer my own question. Stay airside. TACA has a transit counter. For my AV flight to BOG, I had to wait for the gate to open. The BP was printed and waiting for me when I got there.

Caution: the SJO-BOG flight is a F-100 with teeny tiny overhead bins.

Glad to hear it worked out. The airport isn't that large - basically one long building. I thought you would be able to stay airside but wasn't sure. I remember my departure at SJO better than my arrival. It seemed like an easy airport to get around.
