Which company is operating your plane?

CHEEKTOWAGA, N.Y. (WIVB) - The families of Flight 3407 have been fighting for more airline safety since their loved ones were lost almost two years ago. Now, the families are taking their crusade a step higher. They want to ensure passengers know exactly who they're flying with.

A provision of a new law requires vendors selling tickets to disclose the name of the air carrier operating each segment of a flight, but that's not always happening.

Susan Bourque said, "We really are not going away."

The families of Flight 3407 crash victims are keeping the pressure on federal aviation regulators.

"This is pretty simple. This is the law. And the information should be easily visible to a viewer," said Bourque.

They say some internet air travel sites are not complying with a new federal law that requires that the air carrier be disclosed on the "first display of the website following a search of a requested itinerary."

Rep. Chris Lee said, "These are no brainers to get fixed. It needs to get done."

Representatives Chris Lee and Brian Higgins are now calling on the U.S. Department of Transportation to take action against ticket-sellers not complying. In a letter to Transportation Secretary Ray LaHood, they write, "Americans deserve to know who or what is operating the aircraft they are boarding."

"And those who don't comply should be strictly fined for their non-compliance," added Rep. Brian Higgins.

Rep. Lee explained, "The key metrics was to insure that when searched for a flight that you would know who the carrier was. If it was a major airline or if it was a regional carrier."

50 people died when Flight 3407 crashed in Clarence Center almost two years ago. The plane was operated by Colgan Air, a smaller, regional carrier.

Marilyn Kausner said, "Today is my daughter's birthday. She would've been 26-years-old today."

John and Marilyn Kausner lost their daughter, Elly, on Flight 3407.

"Had we known that a small regional carrier was going to be flying her home, we would've booked another flight for her," said Marilyn.

The Kausner's and other family members have been pushing for safety changes in the commercial airline industry.

John said, "That's really our goal is that we really don't have a need to be vigilant anymore. We have one level of safety on every plane, going out of every airport in the United States."

Senators Charles Schumer and Kirsten Gillibrand are also calling on the federal government to fully enforce aviation safety reforms. The penalty for non-compliance could go as high as $27,500 per violation.
