United Airlines buying 777-300ERs?

It has been reported UA will purchase 10 77W's in the near furture. If so, what are the chances of 77W's to replace the current 772's out of SYD, even the Dreamliner out of MEL? Any thoughts would be great.

Then the Dreamliner to Brisbane :)

I see them as replacing the oldest 747s.  I would expect to see SYD replaced with a 789 before a 77W imo.

I dunno, I think SYD might just have enough traffic to justify it during high season.

I would assume that MEL-LAX is a 787 for a good reason. They never found the nonstop MEL route worthwhile until they got the 787 so I assume it matches demand.

As for 773s replacing 772s -- sure, why not? Without access to UA's internal databases, though, I don't think it's possible to do anything better than a vague guess as to which routes they'd find it most profitable to swap out one plane for the other. 

What I really wonder is: will UA take this opportunity to "upgrade" its 777 fleet to ten-abreast seating in economy? 

It would compliment their yuck 'Business class'.

Access to internal data bases?

I always wondered how your info was so good Hugo.
