I do agree with Eloethan's comment as well. If a person is an adherent to a religion that dictates such extreme requirements in a social situation, I do think the onus should be on them to do what they have to do, without impinging on others. If they are flying en mass to Israel, perhaps they should charter a flight so they are all in the same boat or in this case plane together. El Al must know their clientele, surely they should advise Orthodox Jewish men that their requirements cannot be guaranteed and as Holly has pointed out if they prove to be disruptive on the flight they should be removed.
