4X-AXF is from 1978. But the whole fleet of freighters is about the same age:
AXK and AXL are both from 1980 (and were bought by El Al in 1995)
AXM is from 1981 and was added to the fleet in...December 2004 when it was already 23 years old.

For years, El Al has been "on the verge" of getting a new fleet of freighters......but for the time being, there are only those antique, noisy and polluting Jumbos doing the job.

They are not cost efficient, to say the least, and they are really not positive in term of corporate image...
