Since 1973, buses catering for Haredi Jews running from Rockland County and Brooklyn into Manhattan have had separate areas for men and women, allowing passengers to conduct on-board prayer services. Although the lines are privately operated, they serve the general public, and in 2011, the set-up was challenged on grounds of discrimination, and the arrangement was deemed illegal. During 2010–2012, there was much public debate in Israel surrounding the existence of segregated Haredi Mehadrin bus lines (whose policy calls for both men and women to stay in their respective areas: men in the front of the bus, and women in the rear of the bus) following an altercation that occurred after a woman refused to move to the rear of the bus to sit among the women. A subsequent court ruling stated that while voluntary segregation should be allowed, forced separation is unlawful. Israeli national airline El Al has agreed to provide gender-separated flights to cater for Haredi requirements.
