Thought it was quite clear those 330's ain't coming. Especially when reading between the lines on those pilots forum notes. They use the 330 order value to get 320 family aircraft. The 787 and 321 will replace the 330-200's. there will be 2 additional A321's coming as well bringing the total to 8.
My interpretation of those briefing notes was that Gulf Air is in no way interested in spreading it's wings other than they are doing now. They can take on QR and EY with it's current product and some small adjustments. They just need to get a kick up the backside, sort a few issues out and go for it.
