I have already flown DEN-CLE in an E-170 where 5/6 F seats were sold (I got the UG at the gate) and I can tell you that the plane needs better catering and some type of in-flight entertainment if it is to become a standard replacement for a mainline aircraft. However, compared to the Kenjet that I will be flying on going to DEN from CLE in a few weeks, the E-170s are like a Jumbo in comparison.^
I did see some advertising that IFE and wifi were going to be added to these planes but does anyone know, if true, when that will occur?
