From FB and FT: All new companion fare certificates issued after August 1st will be valid in conjunction with Coach Class only. Any unused certificates may still be used towards First Class until their expiration date. Ongoing cost pressures and growing demand for limited space in First Class (particularly on flights to Hawaii and the East Coast) prompted the changes. Our companion fare still offers tremendous value in that - unlike other airlines' offerings - it can be used for travel to anywhere we fly, including Hawaii and Mexico. Additionally, as an MVP Gold, you can still use your benefits to upgrade to First Class when traveling on a companion fare ticket. The hits just keep on coming! Seems like all that's left is the change fee waiver for Golds.
