I believe Vienna t/a is a crewmour that did the rounds after some bright spark spotted it in the timetable for end of April... that being a one off op out, deadhead back deal prior to the flight reductions. Someone ran with it to FB and it went from there... so I don't think it'll be a t/a just yet...
Kiev crew are knackered, and none that I know got any rest
(according to the Book crew should get 30mins on a LHR- YEAH. RIGHT)
