Eric,

The 767ER is included with the 757 because when the airline wanted to operate both types ALPA said, OK if you bring the 757 up to the 767's pay.

My pay category is 76B, there is no 75B. When you see a Delta 757, think 767 because it pays 767.

The 787 is most similar to a 767ER in capacity, isn't it? So NWA was heading that direction.
