I actually feel it’s gotten much better compared to late last year . Yes have I waited recently for gates and ramp congestion no doubt , but nowhere as bad as it was due to very low staffing while recovering from Covid Layoffs .

that being said , if your in 737 please turn on the APU , 2 engine idle (let alone 1 engine idle) just isn’t enough to keep decent air flow in a 737 while waiting for that Gate, The cockpit is much cooler than the folks in the back . You almost have to be cold in the cockpit for it to be decent in the back while on the ground.
