There are very few, if any, majors that will use helo time toward the minimum or even competitive minimums. JetBlue has been known to be helo friendly.

Now, having said that, 50% of my flight time is helo time. I do have >2500 mil MEFW time and >1500 FAR121 MEFW hours. My MEFW time isn't impressive, but it met the minimum hours for a few major carriers. My 4000+ helo time made me and my stories different than the 10,000 other applications in their stack and was one of they keys to getting interview invites...so yes, helo time does count, but probably not until your fixed wing time exceeds the threshold to have your application scored...Good luck!
