Yeah Multi-Engine time isnt the key to regionals any more like it was a few years ago. Before you could get hired sometimes with just 500 TT if you had 100ME - this was a huge advantage to the AllATPs program since they were heavy on ME time.
Now its total time (to qualify for an RATP) that tends to be the limiting factor because they cannot hire you if they cannot get you an ATP by the end of training.
