I'll tell you in about 32 hours or so!
For me very handy - am close to LCY so can (conceivably) do an ex-DUB on a Friday using back to back from the 650 LCY-DUB, then use the >2 hour layover to grab bags from home and check them onto BA001
(That's only my fallback though - am experiencing the delights of the Maldron at Dublin Airport tonight if all goes to plan. A quick DLR / Uber to home may be in order tomorrow to see if I can grab my supercard from mailbox...)
