Current production rates and anticipated testing/validation probably puts delivery midyear. I don't purport to have any inside knowledge, but the time is likely coming soon for reveal of the strongly-rumored Polaris 2.0 seat. My hunch is that we will see a springtime announcement to create a marketing halo around the Polaris product as summer leisure travel is planned.

I also know that United learned from the original Polaris announcement, which left far too much of an interval between launch of the configuration mockup and actual service entry. So that will also likely change.
