I do not have a chip on my shoulder! My original post was just trying to explain that whilst the odd one or two might see moving from the 146 to the 400 a 'demotion' many that have done it haven't felt like this.
Yes, the two a/c are completely different, and each are very good for the routes they operate. The 146 is faster, the 400 has a nicer flightdeck with more advanced systems.
