# 221.205 Justification and explanation for certain fares.

Any carrier or its agent must provide, as to any new or increased bundled or unbundled (whichever is lower) on-demand economy fare in a direct-service market, a comparison between, on the one hand, that proposed fare and, on the other hand, the ceiling fare allowed in that market based on the SFFL.
