No one has mentioned the Forbes article suggesting that the 777Xs were to e swapped for 787s

When the extension of leases on 10 777-300ERs first appear I thought that CX was just trying to reduce CAPEX. Then I came across the suggestion that CX was negotiating the extension of leases on a further 10 units. This seemed strange because the current leases would only expire after 2025. I could only imagine that CX were extending these leases to get some form of near term benefit such as a waiver of lease payments for a period. Now there is the suggestion that the 7777X program may be cancelled in which case half life of existing 777-300ERs from a careful user, never raced or rallied, may have a higher valued than currently anticipated so it may be a good time to secure them at a favourable price.

To me DestinAsian is pointing to CX replacing its regional 777-3003 in 2024 when they will be quite old. interestingly 17 units each with 438 seats gives a total of 7446 seats. If a 787-10 has 350 seats that would equal 21 units.

Is any of it real? I don't know. But a couple of the answers given by Martin Murray in the Analyst Briefing Q&A on the CX web site sounded to me as though he was skating round but close to a hole in the ice. I imagine that a change of that size would have to be announce to the stock exchange but perhaps it would all be finalised so that it could be announced in one singe package. Or maybe they are keeping it for the AGM. Or maybe its just hot air.
