Just booked a holiday to Cancun out of MAN for end of April 2018, and because TUI have re-designed the seat booking process, removing the -90 day restriction when pre booking seats, or atleast Premium Club, was able to see what aircarft we'll be on.
26/4/18 MAN - CUN showing 46 isles on the seat map, indicating a 789 from MAN
Return (for me) 11 days later being a 788.
So it looks like 2018 will see a 789 based at MAN, unless it's a temp swap from LGW. Does this mean that the 2018 fleet of 789s will be 3, as I believe there's another 789 delivered this month, again based at LGW?
