First Time Connecting to LY - Luggage Checked Through?
 

Incredibly enough, this is my first time ever connecting to LY from another carrier (single ticket). I assume my luggage will be checked through but wanted to confirm?

Do I just approach security at the gate as if I was departing with only hand luggage?

Specifically CPT-JNB-TLV, but is it different depending on route?

Gotcha - so in my case, assuming no transfer desk as it's a domestic connection, so will head to the gate. Anyways arriving within 3 hours of the flight

I flew JNB-ZRH-TLV (on Swiss) 10 years ago. The TLV leg was a code-share flight operated by LY. My luggage was checked through and I got both BPs at JNB. I went through El Al security at ZRH with my carry-on only. None of the security questions was about the checked luggage. I assume it should be similar on your itinerary.​​​​​​

Edited to add: they had security at the gate for those who never went landside.

You'd have to change terminals in JNB, and re-clear security (and immigration of course), so there isn't any difference between connecting passengers and passengers flying HBO.
When you head from the domestic to the Int'l terminal, you'll notice signs to security/gates, you should use these ones and not continue to the check-in desks.

So in the end, everyone claimed in Cape Town that there's no way we could check our bags all the way through and we'd have to re-claim. Nonetheless, at check-in, we were asked if we wanted to short-check to JNB or check through to TLV. We checked through and went to the BA baggage desk in JNB to confirm the bags were sent to LY. She said yes.

Went to the gate directly and was required to print a new BP (apparently mobile BP and printed at home BP weren't good enough). At the security interview, they photographed the bag tag.

Nonetheless, my colleague's bag made it while mine didn't.

Recommendation for the future is to wrap your bag in CPT and short-check to JNB, unwrap and head to LY check-in and then re-check the bags (they then wrap for free). Helps ensure the bags made it, ensures you have the proper BP for boarding, and simplifies the security process.

Why would you want to wrap/unwrap etc.?
I agree if you have enough time and not bothered carrying your bag you can short-check it, but in most cases it's not really needed and your bag will make it.

Wrap because of the issues in general in SA with baggage. Unwrap because LY doesn't allow you to arrive at check-in with a wrapped bag in JNB.

Got the bag delivered this evening. Broken
