Flying on El Al's new 747-400s, with personal viewing screens even in coach, the 11-hour flight to Tel Aviv from New York is comfortable. Ask your El Al representative to provide you with copies of their engagingly written information booklet to send to attendees, who need to know, for example, that each one of them will be questioned for up to 30 minutes at check-in about themselves and their itineraries. El Al flies direct from many major cities.
English is the language of business in Israel, and is widely spoken. Sightseeing should be done with a reliable and knowledgeable guide. Highly recommended is Yakov Goldfine. Contact him through the Israel Ministry of Tourism.
