Apologies if this is posted in the wrong forum.
I am a bit confused about SJU. It is marked as Puerto Rico, rather than USA, which means that as a US-based airline I cannot operate flights from SJU to anywhere else in the Caribbean.
Is there a reason for this? In real life SJU is part of the US (domestic flights, US airlines can fly SJU-non US etc.)... Or is it just a bug?
