All I can tell you about the delays on the Embraer, is the same situation each time. Nil spares due to credit/stores/gf supply issues. Nothing out of the norm so far on the aircraft them selves, just a lack of support and acknowledgement from GF...allthe reports this aside so far are very positive...2 x190 on the way later in the year...
Still at least you will be able to compete with the other regions operators now.gf,saudi air,nas, Oman, egypt, royal Jord...Jungle jets are flooding in on orders over the next 3 years.
