I have nothing to really back this up, but for what it's worth the new(ish) B6 service hasn't done much to affect our service down in the Carib from SJU to STT/STX which they started this season (figure this is similar circumstances). And I also read somewhere that the ACK flight will be an evening turn, I don't think it'll have a huge impact on 9K but this is mostly my 2 cents!
