But what is the cost of an A319 divided by the number of seats, vs. that of an EMB190/195 divided by a number of seats? Of course, those types of numbers are always depending on the deal and very confidential, but I suspect the difference would buy lots of seat miles. I suspect that is why Jetblue, like Gulf Air are looking seriously at EMB's.
As for the cargo space issue, it will be interesting to see if the same problem exists without the Inflight Entertainment System.
