You’re very low on hours as it stands now. The average in my class was probably 4000, with most being regional captains or military (this was pre-contract). As for what helps, get to know some JetBlue pilots and establish some internal relationships. Otherwise, apply early and often. At your age, you can probably wrap up a degree (if you don’t have one) and get hired at the legacy of your choice. Quicker upgrade and more defined future, to say the least. Best of luck...
