the best in flight product seems to be on the long haul Hawaii routes at this time. Been consistent with the flight reviews and photos.
Makes some sense since the premium cabins have been selling well on the HI flights. UA seems to be focusing on the premium leisure market at this time. That's the big reason why I've been arguing that the ground experience should match the in flight experience for long haul HI. Instead, we have a mish mash of products with Polaris having the best ground experience, but many are not satisfied by the in flight experience, with the reverse being true for HI
