I'm shocked that you are so clueless about what's going on regarding these leased planes and El Al's pilots.
In short, EL AL has a long dispute with its pilot union and it has been getting nasty over the last few years. Pilots are doing crazy things in order to gain leverage. For instant pilots often cancel the last minute leaving Elal stuck with paying more for their (co worker) friends in order to fly their planes resulting in all pilots secretly collaborating to make more money etc etc - real crazy Jewish shtick and fighting back and forth.
So El Al tried to fight back with these leased planes that are not officially operated by LY and therefore they can use other pilots which are not in union..
Bottom line, please do your research and you'll see that it's not so simple as you described it in the DD post.
