Also note these differences, maybe just semantics, but differences all the same.

UAL MEC Chair: "...consider it for acceptance"

CAL MEC Chair: "discuss...the anticipated timeline for completion and consideration ..."

UAL MEC Chair: "We are United,

Chairman, United Master Executive Council "

CAL MEC Chair: nothing posted by poster so who knows how his signature went but maybe this is it "CAL MEC Chairman"

See what you want but words reveal much so you all make your own conclusions.
