the 140's aren't crap. i much prefer them to the 145's. they're not underpowered, i was doing 3000 fpm yesterday out of MSP nearly full. the sunshades and FMS makes it tons better than the 145. I rarely have a broken plane on the AA side. The 145's are always broke. While they are overweight with 44 adults and 60 bags, that not an airplane issue, that's a weight and balance number issue.
