Complaints against airlines continue to rise.
FOX News Radio's Lisa Lacerra reports:
The Department of Transportation saying it received more complaints against airliners from consumers in March than the previous month or March of 2014.
Passengers on Frontier Airlines 34 times more likely to complain than passengers on Southwest, which has the lowest complaint rate.
Frontier and Spirit, the airline with the second highest complaint rate, are ultra low cost carriers that charge low fares but add fees for many things like carry-ons and seat assignments.
Hawaiian Airlines, blessed by usually good weather and lots of short flights in its home state, ranked best.
Envoy Air, a regional carrier that operates many American Eagle flights, had the highest rates for canceled flights and lost or damaged bags.
