For some reason I remember someone mentioning that you could only upgrade the transatlantic portion not all segements....but dont hold me to that. It does make sense however as I believe you only get one cert per e-SWU that they convert to paper. You will rank behind all the LH people and other *G that are on the upgrade list but I have heard success from others in their ability to upgrade. I would however be prepared to sit in Y. Hope this helps.
