In reference to last ATC conversation, did the MH370 ever read back the new frequency?
All the casual stuff about good night etc. is not an issue, as this is normal, however 2 things that you would expect that is not specified in the transcript, and that is why was not the new frequency read back, and the aircraft's call-sign?
These might be small details in the big picture, however sometimes the devil lies in the detail.
Why would they fly at 29.500 (FL295)
How has the documentation of the inital climb to FL450 - then FL230 and then FL295 - during same time new tracks.
To many questions and not enough answers.
