Tons of options in today's aviation industry. Several guys heading to the regionals now. I've heard of people heading out west to Surf Air.
I get this question a lot. If your end goal is to go to a major airline, Boutique isn't your best bet to "skip" the regionals. Maybe that'll change in the future but who knows. Boutique definitely is an awesome way to get your foot in the door and open up several new opportunities down the road, though.
