Just to clarify, as of today 192 Airbuses are on firm order or have been delivered.
The timeline runs:
120 Orders and 120 Options 30th Deb 2002
20 Options turned into Orders 22nd Dec 2005
52 Options turned into Orders Today
----
192 Orders used out of original 120 Orders + 120 Options
----
48 Options presumably still on the books but not seen an explicit reference.
75 New options announced.
Cheers
