More space in the Lounges, even J lounge overflows often and because of this I prefer to be at the gate rather than in a crowded lounge.
Second problem then arrises, needing to get onto the plane early (single body aircraft only) to secure overhead space. This means lining up early with often 50+ people. What a drag.
I'd like to see priority boarding for elites domestically - to be in line with every other oneworld carrier in every other country.
