Incorrect. Only 4 of 9 A321neo's delivered with the P&W engines have been delivered since JetBlue got theirs. Of those 9, none were to a repeat customer, and all came from the XFW factory. 8 had the space flex cabin.

Of the 11 A320's delivered since JetBlue got theirs with P&W engines, which are a different variant, 3 were to a single customer, and only 3 came from the XFW factory. IndiGo was that customer, which placed their order for 280 A320neo family aircraft on June 22, 2011, making them the third customer to place an order for the family of aircraft. With the size of the order and when the order was placed, along with the delivery slots they had, early+current delivery delays, it's no surprise they are taking more deliveries than JetBlue currently.

To summarize: 15 A32xneo planes with P&W engines delivered from June 29-today, 16 including JB. 3 went to a single customer.

You are fake news

Edit: I would like to add that IndiGo is the largest customer of the A320neo family with a total of 430 aircraft on order. 280 being for the P&W engines.
