Looks like those blue chips will not be loaded on JetBlue aircraft with union labels attached anytime soon.

The IAM’s effort to become the representative for JetBlue’s employees involved in ground operations, provisioning, and other related positions was dismissed by the National Mediation Board today.

The NMB dismissed the petition because the union failed to produce evidence that at least 35% of the eligible employees had supported holding a representational election.

JetBlue remains the largest airline with no union representation of its employees.
