i heard that the guys from upstairs are rethinking about the removal of first class
.because the regional jets would be fully Y class and the 330s will only Y/J( and that would not be a little weird)i wont mind if the airlines fleets would mainly consists of the 320.because they are reliable and fuel efficient. However, there are countless number of business pax flying to dubai and Kuwait almost every day. And the flights are mostly fully( occupied by business travellers).
and to accommodate the business travelers the airline would need at least J class( no rich Arab is ready to fly Y class
)from what i know the E-190s are almost exactly similar to the 319s .
As it would be easier for the airline to go all airbus until the 787s arrive .
