That, and the relatively small world wide fleet size, and the end of production, is going to create pressure to downsize or eliminate the A380 sooner rather than later.
There will be ~250 A380's flying into the foreseeable future.
The lack of future a380ceo or A380neo orders means there will be no incentive for the engine makers to improve performance on the existing engines. The A380 performance will thus be frozen in time as of the last A380 PIP, as the competition between all the big twins will drive PIPs and NEOs for them. The end of A380 production will drive up the cost of high wear spares. The relatively small fleet size and high cost of spares means there will be few facilities to do heavy maintenance and it will be costly.
Basic economics shows us we can foresee a future where less than 250 A380s will be flying. IMHO this will be sooner than many here seem to think.
... the A380 which is OT for this thread.
It is on topic because Airbus offered a package of A350-1000 and A380 against Boeing's 77W and 77X which we now know has lost, despite BA already having A380 and A350-1000 in house or on order.
In the bigger picture, the whole narrative that BA would pick up used A380s in the near future, and A380 would stay in production and spawn an UltraFan A380neo in the mid 2020s, and the A350-1000 would squeeze out the 77W and 779 because only the ME3 would buy it, and there would be an A350neo in 2025, has been in its terminal phase for the last few weeks and IMHO has died today. In this time frame BA has rejected more A350-1000 and A380s and has bought more end of the line 77Ws (!) and now 779s which is a remarkable turn of events given how influential BA is, IMHO.
