Supreme Court Won't Hear Plane Ticket Price Case

Law requires airlines to include full cost in ads, including taxes and government fees

The Supreme Court on Monday declined to hear a challenge to a federal government rule that requires airlines to advertise the full cost of tickets.

Allegiant Travel Co, Southwest Airlines Co and Spirit Airlines Inc had all challenged the U.S. Department of Transportation's regulation, which prohibits airlines from leaving taxes and government fees out of their advertised rates.

A three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit upheld the rule in July on a 2-1 vote.
