Elal changes aircraft more than any other airline
False. Where do you take that from? I take my info from thousands of flights booked (as a TA), and I nice percentage of them on El Al. Again, I'm not referring to changes more than 3-4 months prior to the flight. That's a very different story (with all airlines).
They had issues for a couple of months last year when they were wetleasing from Privilege Style and Hi Fly, but other than that period of time, they were pretty reliable.
