ONE OF the major US carriers, US Airways, has been fined $US40,000 by the US Department of Transportation for violating US consumer laws that require full disclosure of advertised air fares.

DOT said its Aviation Enforcement Office found that US Airways listed fares on its website "that did not include additional applicable taxes and fees, or any notice on that page that these additional charges would be required" on certain lists generated by customer searches for one-way flights.

ATWOline reported that the agency again warned airlines that, under US law, either the entire fare must be indicated on the first page listing price quotes or "the existence of additional government-imposed per-passenger charges must be prominently disclosed along with a hyperlink that takes consumers to a page that describes the additional charges".
