FTB;

This is not an answer to you question, but just a tag-on for more info. Operationally, the E190 has not been the stellar reliability performer that the operators hoped it would be. I do not have complete details on its shortcomings (some of which have been sorted out), but for this reason, the E190 carries a mainline question mark.

I heard a funny new nam for an airplane. Apparently quantas calls the A380 the A180 because when it pushes off the gate it does a 180 and goes back to it.
