I don't expect Tim Clark is going to roll over any more than DL is.
Difference is that DL is a US citizen; neither EK or Tim Clark is.
just because a US citizen has provided communication to an official of the US government does not make it public material.
further, your continued antagonism of DL interest on this issue shows how on yet another issue you and the IAM are not interested in the interests of DL employees who are smart enough to realize that the ME3 is fully devoted to gaining access to and taking revenue in the N. Atlantic market from US carriers - at the cost of DL jobs.
Even if you really personally support the ME3, given your clear position of advocacy for the IAM, you would be smart to shut your trap about the ME3 or at least put on a fake "I hope the US3 wins" face.
once again, this is not about DL or Tim Clark. It is about the US big 3 - AA, DL, and UA - who jointly delivered the report to the US government.
If you had half a functioning brain - which is highly questionable - you would desist from your cheerleading for causes that are clearly contrary to your own current constituents which includes US3 employees as well as DL FAs who you would love to represent but who are not about to harm their own future by supporting an organization that is working against them - whether it be for Boeing employees or the ME3.
