This means that these planes will not be upgraded. The question remains, as in my OP (which Andrew Yiu indicates that the info is proprietary and confidential for now) - as to whether these planes will be replaced (when the leases run out) with domestic configuration business class planes, which will only serve the domestic market, or with the newer planes with flat bed seats, which will fly on the domestic routes in conjunction with the longer-haul overseas international routes. I guess we will eventually find out the answer to the question.
