Wondering about a BA Silver (OW sapphire) flying on AS LAX-NAS. Definitely more than 2000 miles and part of a RTW that started in Japan, etc. I believe that all of the OW terminals are connected after security, though a long walk to AS's terminal.

Distance is not important. As a BAEC Silver, you are non US oneworld Sapphire and have access to any oneworld lounge before a oneworld marketed and operated flight irrespective of class of service.

You also have access to the AA Flagship lounge in T4 as a oneworld Sapphire. IMHO that is a better option than the *O lounge.

It is a 10-15 minutes walk between the TBIT *O lounge and the AS lounge at T6.

100% agree, the AA Flagship Lounge is much better than the QF Business lounge in TBIT. I walked all the way to TBIT in December thinking I was going to the QF F lounge but it was closed. I tried the business lounge instead and was pretty disappointed. I don't think going to TBIT is worth it unless you're leaving from that terminal or OW Emerald. (and the QF F lounge is actually open)

Would these options be the same for Finnair paid biz class sold as AA codeshare? Can I access the lounge in the morning for an evening flight? I am planning a long layover.

Yes & Yes. There are also three Admirals Clubs you can check out should you wish.

Just for further clarification, it could be an AY tix without any codeshare required, and even award biz flights would qualify as an award basically equals "paid by miles".

And you can pop your head into the Admirals Club adjacent to the AA FL to check it out. By far the best views, but nowhere the F&B compared to the other options available to you.

Just back from visiting the AA flagship lounge, QF business class lounge, and the AS lounge (I was flying AS LAX-NAS) during breakfast and lunch.

Breakfast - AA far and away the best, variety and interesting dishes. QF was similar to a buffet at a low end hotel. AS was in between, though make your own pancakes.
Lunch - AA still the best of the 3. QF improved but less variety, though the soup was excellent. AS - did not use.

As to alcoholic beverages, AA had good variety of wines and Piper Heidsek Champagne, QF had a good Chardonnay, but nothing else appealled to me (standard bold clumsy reds), AS did not try. I don't drink beer or spirits.

Just to clarify, it's not called the QF business Class Lounge (albeit operated by QF), but The Los Angeles Business Lounge, is case someone is new to TBIT lounges goes looking for it.

But yes, the AA FL is best of the crop, unless one has access to QF First Lounge.

Ok here is a fun one. Booked a Condor Business class ticket LAX-FRA in June. Used AS and the ticket number shows 027 and reservation is in the Alaska app. As a OW emerald will I be able to use all the TBIT lounges I normally do flying a OW airline? Really want the wife to experience the Qantas First lounge as it is the best of the bunch in TBIT i think.

No. Condor is not a Oneworld member. You must be flying a Oneworld member airline to access Oneworld lounges either based on status or class of service. Ticket stock doesn’t matter.

What if it was ticketed as a codeshare so full Alaska flight number etc?

That will not make a difference for access to the QF Oneworld lounge as the flight must be marketed and operated by a Oneworld member airline.

Sadly seems you'll be given access to whatever lounge Condor gives you a voucher for. Being booked as an AS codeshare has zero bearing.

Personally I'd love it if they joined oneworld in the future to have a carrier in central-ish Europe again but that's not even in the rumor mill. While not a premium airline, it doesn't seem too bad from what I've seen on YT.

BAEC Gold/OWE LAX Access with JL Arrival and DL connection
 

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?

It's an interesting one. I think you can get into the AA FL with your inbound boarding pass and shower there plus get a decent bite to eat. Good luck with the TBIT lounges since QF controls those and they seem to hate life in general, let alone people not flying out on international flights that day. The AA lounge is a good hike from DL's terminal but is likely your only option, assuming they don't check your onward flight (they never have with me)

I guess there's no choice of going LAX-SLC on AA to simplify things?
