Interesting that MA has e-tickets down pat already yet isn't being allowed to join for another 4+ months ... due to the other inter-operability requirements (little things like common baggage tracking, etc.). Makes me wonder when RJ will be joining, they seem to be struggling to get ready.
As an aside, MA has announced a >50% increase in their long-haul fleet (but don't get too excited, they are adding 1 767-300 to their existing 2x762 fleet). So looks like MA has big plans from joining Oneworld.
