The money for new aircraft was secured in format of a loan from the Governments of Oman and Bahrain earlier this year. If I am not mistaken, it was around $800,000,000 USD.
As far as aircraft type, from where, when, etc . . . those who are talking don't know and those who know aren't talking. For my part though, I sure hope they don't get any more ex-Royal Jordanian birds.
The Boeing 767's are old and tired, and in the opinion of many, desperately need to be replaced. The Company mused reducing the fleet to possibly only two types of aircraft.
There has been plenty of navel gazing during the last few months about aircraft replacements, CEO replacements, etc. Fortunately the infiernal temperatures and humidity have either kept most of us dozy or prioritizing about trying to stay cool.
