"Priority" baggage
 

Does it really work for anyone?
Regardless of origin/destination my bags are never among the first ones on the belt with El Al. Wondering if it's just my bad luck or at TLV they completely ignore the priority labels when loading/unloading the bags.

ELAL ignores them.
I flew with DL to TLV a couple of days ago, and priority bags came out first.
So it is an LY issue.

in most flights and airlines i flew with it didn't work

It varies. I’ve had my bags come out first and I’ve had them come out nearly last nits depending on ground crew working the aircraft. I’d guess there is a limited number of things EL Al can do!
