In answer to your question about what is wrong with the J41, for one thing the seats are so narrow that they can't have armrests. If they did, no one could fit into them. Another thing is that they have no overhead bins or underseat space, so you have to leave your carry-on bag outside and they put it somewhere. I don't like my valuables out of my sight, and I can't fit them all in my pockets, such as money, tickets, passport, hotel vouchers, etc. Also, it feels like a toy airplane. Why can't they make commuter cabins as roomy as the small piston aircraft that used to fly those routes, such as the Convair 440 and Martin 4-0-4?
