When airlines take delivery of new jets, they tend to try and space them out a bit. The ability to add a bunch of jets at once is limited so you don’t often see a lot of jets from the same airline on the flight line at the factory. However, there has been a cluster of Vistara 787s at Paine Field recently. I think they were originally assigned to another carrier that couldn’t take delivery of them – perhaps Hainan. Consequently, they have been reallocated at short notice and Vistara is the customer. Here they were sitting together in Everett going through the final phases of testing. I’m not sure whether some will be stored and delivered later or whether they will all go in a group.
