Just for curiosity, will A320 operate European routes even after A330 being delivered?
Are Saudia's A320 equiped with ACT? It seems quite a long way to Europe on A320 even with frew pax. I use to operate A320 on full charter configuration and one of our destinations were around 2,500 NM and had the reduce the capacity from 174 to 144 seats.
How long are your layovers in Europe?
Happy landings
