Many people here question the A330neo in general. I think it is too early to say that the program is doomed to fail. Apart from the fact that the classic A330 was a best seller, the factor of the range shouldn’t be underestimated. The A350, B787 and B777X have all way longer ranges, capacities which aren’t needed by all airlines. This can be a reason that airlines don’t order these aircraft.
An example: The 777X had an excellent start after publication of the program as the gulf carriers ordered hundereds of it, but since then there weren’t many orders coming in at all for three years (total about 340 including both 777-8 and -9)
So in fact, the A330neo will be the only alternative aircraft of the new generation in this range segment until Boeing unveils the plans for the 797 (name not confirmed yet). I think this plane has a chance to get many orders in the future.
