I hope the MOD's will allow me this one transgression of cross posting:

Folks, anyone travelling on the 787 tomorrow or Friday should check with BA.com and MMB to see if they are still flying before heading to the airport (if you are going solely to try the 787 out and not simply to get from A to B, I'm sure the 767 can and may be substituted if the checks do need to take place during the next day or two)

It appears there are some checks that will likely be done on them over the next few days so worth checking here and the various other sources you may have along with BA.com or in MMB before you make the journey.

Thanks. ^
