Continental and Eastern never merged. They were both own by Texas Air, and operated separately, same as British Airways and Iberia have common owner today.
OnePass was not EA's original frequent flyer program. After Texas Air acquired Eastern they created OnePass to be a joint frequent flyer program for Continental, Eastern and some affiliated carriers. See AP article reporting creation of OnePass in May 1987
