Can someone explain the different 763s?
Delta currently runs 4 versions of the 763ER:

76L (36J / 32C+ / 143 Y)

76T (36J / 29C+ / 143 Y)

76Z1 (26J/35C+ / 165 Y)

76Z2 (26J/29C+ / 179Y)

Other than the seat differences, and the fact that the Z2 is the only one that offers L2 boarding, can someone explain the other substantive differences? I occasionally see people talk about how different models are converted to others, but is there something else about the soft product or engine or something I’m missing?
