I think when a plane fly over desert ETOPS operations also apply, and now Airbus has ETOPS 120' for A320-family
Other hand, A319 is for me, a state-of-art aircraft.I really do like it.According to a friend of mine (AF staff) AF
will fly to SSG (Malabo) with a new A319ER, and a fly CDG
-SSG is longer than a MAD
-LOS.Unless 100 minutes more.
A319 is a GREAT plane.Airlines like IB
,AF and even a low-cost like Easyjet are very happy with them.
