Senators who approved the legislation said a five-year plan, which hasn't been passed since the 1980s, added stability and improved passengers' flying experience.
"In creating new protections and enhancements for the flying public, this bill creates five years of stable policy direction for the aviation community," Commerce Chairman John Thune, R-S.D., said in a statement.
According to the Washington Post, some of the changes the bill will make include: prohibiting airlines from bumping a passenger who has already been seated; requiring the FAA to set minimum seat widths and distances between rows of seats; and permitting the Transportation Department to determine if airlines are justifiably blaming delays and cancellations on weather.
The bill allocates $90 billion to federal aviation programs over the next five years, according to NPR. That amount does not include a proposed increase in the $4.50-per-ticket passenger facility charge.
