So you're effectively silver until 2023, bronze until 2024. By 2024 the airline landscape might be totally different - we could see lounges on a subscription basis like in the US (where even full-fare domestic first class won't do), we could see economy cut up like EasyJet (must get up-front economy to bring a large cabin bag), and so on. No point thinking too far ahead!
Yest I'm not really sure what problem the OP has.
