No plans exist for A330 replacement within the next two years. SN
was even looking for an extra one, but couldn't get hold on (it seems if any A330 become available they get very soon re-allocated.....credit to this aircraft??). On the other hand, the A330's seem to be plagued by a lot of technical downtime lately. Aren't those A330 original Air Inter airframes? This makes them amongst the oldest ones flying.
Same goes for the Avro's: no replacement within two years.
Didn't VEX some time back (pre-Sabena failure) order B737-700's, but never received them because they went straight to Virgin Blue?
VEX didn't merge with SN
, they are just owned by the same investor. Resources and their usage remains split (for now).
