While I can get 'consolidator' fares on CX and even SQ sometimes. EK's consolidator contracts seemed to have dried up in the US. I can tell from the UAE Skywards cash plus miles awards that except for Houston, they have no need to promote sells into economy from the other locations. So, if it is still 2009 for your booking, I would book online via emirates.com to get the online bonus credit since all the travel agents were offering same fare or even higher for some reason (few dollars for their trouble I guess).

There was a free companion offer for first and business via emirates.com US site a few months ago, but that is also now gone.
