Airbus CEO on Indian big order from IndiGo (500 aircraft), and Air India (290 aircraft). Shown Air India under new ownership also increase their fleet options to counter IndoGo.
In the interview, Blomberg ask him on potential vertical intergrations (Thus the aircraft manufacturer buy engine producers). Something that Airbus CEO pointed it is not efficient as means the aircraft OEM tied up to only one option.
Still I got impression that the business model still going to relies on engine manufacturer to come out with new efficient engine, toward future iterations on existing airframes. Which is understandable cause building new airframes model is very expensive.
Airbus seems talk on A220-500 is the only potential on new model. At least in foreseeable future.
