@JetBlue hi. I have a JetBlue SJU-JFK next week and a JetBlue mile redemption ticketed JAL F ticket JFK-HND 4h after arrival. I know it is a diff terminal, but can I 1) check through bags 2) have the JL F baggage allowance (or 2x70lb bags at least) for sju-jfk?

I’m mosaic if that matters, but there is no mint on the Sju-jfk flight needed for schedule, and have the JetBlue plus card. I’d prefer not to pay $150 for overweight bag if possible.
