I have fond memories of CP F28's on RDU-YYZ and RDU-YOW, especially after the ex-BA seats went into F. But F28's are hopeless. Only about one-third of the F28's built are still flying, generally as private jets or in third-world countries. Some of CP's F28's were built in the early 1970s. There are plenty of F100's and F70's built in the 1990s that could be pulled out of desert storage.
