What's not yet clear, however, is what variant of 787 will be used. United does have a number of 787-10s on order — the stretched-out version that we saw evacuate Charleston ahead of Hurricane Florence — so it's not out of the realm of feasibility that we'd see those slotted in here. The airline had scheduled for its first 787-10 deliveries to enter the fleet later this year, though it also has existing orders for the 787-9. United's 787-10 will be the first Dreamliner to offer a modified version of the airline’s new Polaris business-class seat, which may eventually make its way to United’s smaller 787-8s and -9s.

In March, Singapore Airlines took delivery of the first-ever 787-10 Dreamliner from Boeing. It has a total of 49 ordered. Other carriers that have placed orders for the -10 include Etihad (30), British Airways (12) and Air France-KLM (8), among others.
