I dont think UA has meals on the EWR-HNL in main cabin, so I dont think any of the carriers are rushing to do this

I remember in the mid-2000s CO was the only airline still offering meals to all Y passengers and it was a huge marketing campaign for them. I remember flying them for a mileage run when they were still sky team and I got the meal. and let's just say it wasn't anything worth clamoring for
