Reid said that after emerging from conference with the GOP-controlled House the bill was not perfect, but nonetheless critical.

"People worked extremely hard on this," said Reid. "This is not a perfect piece of legislation, no, it isn't but we have not had an FAA bill since 2003... I repeat, this bill is not perfect but it's something that is extremely important for job creation and for making our airports more safe."

The Senate will return at 2 p.m. on Monday and that vote will take place at 5:30 p.m.
