EL AL Matmid - el al cargo

Anyone ever use it to ship personal items?

I have about 350 pounds worth of stuff I need to bring on a trip (some heavy books and some sports equipment, bikes).

Yes...

great-
how did you find the experience?
Pricing?
drop off and pick up?
any customs issues for those coming in on tourist visas?

If I were you I would just use one of the established shipping companies and not work directly with any one airline.
