Unfortunately, I don't think they are getting more a331 this year than previously reported. I saw the internal email that said all 11 a321s next year will be mint configured. 5 of which are lr variant. Imo, still barely covers the new mint routes they added since 2020.
I have also heard they are looking into new configuration for the post merger world. I would be very surprised if we don't start seeing domestic first on a321s.
