I couldn't find the answer to this situation where I'm a BAEC Gold/OWE arriving from HND on JL 16 and have yet to choose onward flights to TWF which is only served by DL from SLC. I have quite a few choices, but really prefer to access an LAX lounge for a shower and decent F&B on arrival. I know if the onward connection is AA or AS I'm good to go, but then would have to collect bags in SLC and recheck on DL to get home. This limits my choices to less preferable options (e.g., long layovers, short connections, slight delay impacting SLC recheck).

The DL option involves the INTL to DOM recheck and TSA screening in the terminal next to TB, then walk back to TB (or even T4) for lounge access. I keep seeing that lounge access is not allowed without an onward connection and presume this is intented to be on a OW flight. Didn't see anything about non-OW onward flight. Understand that many airports would prevent such an option, but LAX now has that ability for airside access.

Thoughts?
