A220 Deliveries in 2018

How many A220 will be delivered this year? Well, if you read the Airbus Q3 Press Release, it will be 31. The press release said it will be 18 deliveries, counted from July 1st, when Airbus took over the program. There were 13 deliveries between January and June 30th, so in total that would be 31.
But I would say this is the upper limit. It could also be "just" 30.
Looking at specific customers it is unlikely they will get another four aircraft this year besides the first one delivered. Why: let's count:
The first aircraft for Delta, MSN 50020, was the 23rd aircraft for this year. Next in line to be handed over is 55044, a A220-300 (CS300) for Swiss. This could happen as early as tomorrow.
Then 55042 for Air Baltic should be the next one, having it's first flight on October 30th. Expect delivery in 2-3 weeks. Also 55045, again for Swiss, is waiting for the first flight - that should be every day now, as it is already a week late. We should expect a handover in late November.
The second Delta aircraft, 50021, is just before the pre-delivery stage. If it moves to the flightline quickly and gets through the test and customer acceptance flights as smooth as the first one, it could be handed over to Delta in late November as well.
That would be 27 until the end of November then. Then there is also 55037 for Korean Airlines and 55046, another one for Swiss. An the third one for Delta, 50022, could m ake it to the customer this year as well. These would be 30 then. I don't think that we will see 50018, on of the two remaining CS100 (A220-100) for Swiss getting ready this year. So Tanzania could be the customer of the 31st and final aircraft this year.
Remember that Bombardier said that they would ship 40 aircraft this year...
