Currently LT PLT on AA. Don't plan on making the minimum spend on AA for OWE so I'm considering changing programs with the following:

2021 travel: Jan: AA I fare SEA-MIA-BZE-DFW-SEA 6300 miles
Aug - Dec: DONE RTW D fare CPT-DOH-MAD-CMN-CAI-LHR-HKG-BKK 20,000 miles

2022 travel: BKK-KUL-MNL-NRT-DFW-GUA-MIA-SEA-DOH-CPT 27,700 miles
Possibly another RTW end of 2022

Questions
For members asking for information, to help people to assist you, can you please provide:
(1) What is most important to you in a FFP?
Lounge access and accruing maximum miles for award travel.
(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
~50,000 16-20
(3) What types of fares do you usually buy?
domestic first, international business
(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Yes. Pleasure
(5) Which routes and airlines do you fly most often?
OW RTW, US domestic
(6) What is your home airport?
SEA but leaving for 2+ years
(7) Do you have FFP status of any kind in OW or other airline? What is it? Do you have any miles banked in a FFP?
AA LT PLT 400,000 miles
BA 100,000 miles
AS 135,000 miles
UA 100,000 miles
(8) Preferred Airlines? Most common Airlines flown on?

I was thinking that AS might be the best shot at OWE for first class lounge but accruing and using miles is more important.

Thanks
