Ah good. Yes there was a post somewhere repeating what sounded like galley FM that MAD was going to join the Long band (and it made me wonder where else would be adjusted), but certainly there was previous speculations specific to this route. Good to see it happening.

EDIT: It would be good to get reports on these routes, outside Breakfast times:
LHR-VIE
LGW-OPO
LHR-BLQ (shorter than MAD)
LHR-PMI
