UPDATE as of 1/27/15
After 2 weeks of trying to work it out directly with Emirates and to get Alaska to try and help to no avail, I resorted to my last course of action.
I filed a complaint with the DOT. In my case I had tickets that were ticketed in First on 2 OCT 2014. My contention was I paid for a ticket (how in this case at the time of booking was irrelevant) with certain services and then the carrier changed the terms on me without notice in violation of their terms of carriage posted on their website.
I provided my e-ticket number along with my Emirates booking confirmation code to the DOT representative that contacted me right away after filing the complaint. He agreed with me that I had a legitimate issue with them but said he couldn’t force them to comply, only issue a violation if they did not remedy the situation. Within 2 days Emirates reversed course and gave me the Chauffeur Drive. Sad it took all that to get them to do the right thing. I wouldn’t have cared but in my case it was going to cost me well over $600 one way for a large sedan to drive me to Abu Dhabi, so I’m glad I did.
Best of luck to everyone else!
