The latest "hoc" - There was a glitch in the El Al computers and prices went really low. People bought tickets ['Jew' bi-gimatria 'metzia'].

Don't want to rain on anybody's parade but it sounds halachically questionable to me. It was a mistake. Makes my moral compass wave rapidly. So if you DID buy a ticket I would ask a shyla. Nobody would want to come to the Holy Land through unholy means....

PS - I heard that EL AL is honoring the tickets. That might spell mechila.....
