MCO is very senior and in my opinion JetBlue is not worth the commute while you wait for your seniority to build up. Once you end up holding MCO you be at bottom of the list for a long time and reserve rules at JetBlue are one of the worst in the industry. We have plenty of pilots that live in MCO area and they choose to commute to JFK just to get off of reserve. Mid-seniority MCO Airbus FO can actually be a line holding Airbus CA in JFK... Something to think about.
