The FAA Reauthorization Act hit the Senate floor Wednesday evening. But before debate began, the legislation was held up by a Tennessee Senator. YNN’s Jennifer Bernstein tells us what Flight 3407 families did to ensure it wasn’t stalled.

WASHINGTON D.C. -- Flight 3407 families packed their bags once again this week and headed to Washington, D.C., in hopes the FAA Reauthorization Act would finally get passed. But before the airline safety bill hit the Senate floor, it was held up.

"My message to the Senate is work together, play nice with each other. This is what we put you here in D.C. to do- to do your job," said Kevin Kuwik who lost his girlfriend Lorin Maurer in the crash.

Tennessee Senator Bob Corker put a hold on the legislation. FedEx, which is located in his state, was lobbying against it because it would affect whether FedEx employees could unionize. Families pleaded with Corker and the Senate to move forward with the bill they've been pushing for.

"We've done what we're supposed to do since last May. We've done everything. We've had meetings, we've sent the letters, we've sent the e-mails. We can't do anything else," said Kuwik.

"The first thing we are here to do, and I think I speak to everyone here, is to urge, plead, beg, Senator Corker to lift his hold and let the bill move forward," said New York Senator Charles Schumer.

Family members met with Corker's staffers in the afternoon. Just a few minutes later they were pulled back into his office, and told the hold was lifted. Despite the setback, the bill will now be debated over the next few days.

It's hitting the floor with bi-partisan support. Schumer announced Massachusetts’s Senator, and Republican Scott Brown signed on as the bill's lead cosponsor.

"We will do everything we can, to make sure that this doesn't happen again," said Schumer.

The legislation is expected to be voted on in the Senate by sometime next week.

"If there was ever a story that deserved to have a positive ending, this was the one," said Kuwik.
