121.311 (c)(3) gives United the way out:
This section does not prohibit the certificate holder from providing child restraint systems authorized by this section or, consistent with safe operating practices, determining the most appropriate passenger seat location for the child restraint system.
United could just determine that the most appropriate seat is one in the economy or Premium Plus cabin. (The one time I was trying to use the car seat, they did tell us that we could just sit in a different cabin).
