El Al airline has published a information brochure for its religious Jewish passengers who sometimes disturb other people by flooding the aisles to pray during flights, giving them information on how to pray seated. Many observant Jews rise from their seats on flights to and from Israel to worship in accordance with ritual law dictating they pray three times a day. They sometimes jostle sleeping passengers and block the aisles, leading to confrontations with secular travelers. El Al has now distributed the "Handbook for Observant El Al passengers" to religious Jewish communities, detailing proper flight etiquette. The publication was written by rabbis. "There is no sin involved in the action of sitting," its reads, and: "It is preferable to pray in small groups in one's seat, on the condition that there is no exposure of nakedness in that area," referring to some passengers' dressing.
