The planes are older but they are comfortable. More comfortable in F than on AA or UA's Hawaiian cattle cars.
Entertainment was severly lacking. 1 movie off a central screen. Food was good, drinks were good. Ground service in SFO was a zoo, as it's done by US Air and I'd say (at the risk of getting flamed) the typical HA coach PAX is not your typical FF so the process was lengthy. However hidden away there is a F check in line which was very smooth. You can also now use the US lounge. Well, that's SF not LAX but overall the experience was good.
Had I known however the miles were not going toward EXP qualification I might not have done it. The lure was a discounted non-refundable F fare that AA couldn't or wouldn't match
