There is some concern about A350 delivery rates. Airbus hopes to deliver 80 this year, which averages about seven per month. Airbus reported six deliveries through February. So they are behind.
Then you see images like this on social media (source A350blog on Twitter) dated March 21.
And this one on Flickr (from A380_TLS_A350) dated March 24 of the Airbus Delivery Centre in Toulouse. There are a bunch of A350s waiting to get delivered.
It is clear Airbus is having a tough time getting deliveries to customers. Â But it would also be fair to say Airbus is moving down the learning curve as the next chart illustrates.
