I searched but couldn't seem to find a definitive answer...

On the LGA-ATL flights during meal times...are the first class meals the "normal" (meaning hot) first class meals...or the ones served on regional jets (cold meals).

So for instance on a morning flight on a 757 (which should have ovens) do they serve omelets or does everyone just get the cereal/yogurt/fruit tray they give on regional jets?
