Hi,
I flew on an Air Wis United Express 146 from Springfield MO (SGF)to DEN last year. It had the same size overhead bins as last 146 I flew back when PSA used them on LAX to Sacremento flights 20 years ago. Back then I could not fit an original Compaq Portable in the overhead bin because they are not tall enough. Now, I could fit a rollabord in horizontally ( not wheel end in ) but it would not have fit if it had been bulgingly full.
