Well good ol' Tom Bradley terminal 4 has changed the baggage check procedures yet again. One now must first check-in and get baggage tags then go to the security screening then make sure your bags get to airline before going to the gate.
Before one had to screen the bags then check it in. Then for awhile for certain class travellers, they had the screening right at the check in counter (For SIA) which was hella convenient.
If you're transitting, this new procedure is ONLY for Terminal 4 International airlines. Other airlines like United, NW and a few others have yet again different procedures.
Of course my 3 bags DID NOT make it with me on my flights since I had to line up at the security screening to find out I had to check in first then line up again. Spent 1.5 hours doing that. Then had to wait for rap singer Eve's entourage to go through security before I could.
Just fyi for LAX travellers.
