I was held back by security due to the countries I have traveled to in the past, and then forced to check my carry-on baggage in addition to my luggage. Both bags were missing upon arrival. Claim was filed. 48h hours later, suitcase shows up with the delivery tag of the carry-on and carry-on is still missing. I bought some items while I waited and I believe the airline will cover up to $150/day after 24h.

I'm on a birthright program, multiple participants experienced this but all got their luggage already and I am the only one missing a bag now, that I was forced to check-in.

Questions:
If the carry-on doesn't show up, how much is El Al liable for? LAX to TLV.
In this case, should I go to the police in the US once I land back and file a police report?
I was treated extremely poorly by El Al security during check-in... do these people steal in addition to being rude?

I don't plan on ever flying with El Al ever again and I encourage others to do the same.
