I'm flying onMonday from Manchester. Booked last summer, the flight times did change in the autumn, put back by a couple of hours both ends, but only to what the normal times usually are anyway. The flights I originally booked were unusually early. Fingers crossed no nasty surprises in the next couple of days! But I've not yet had a journey there with Virgin that's not been changed in some way, since I first started going in 2014. And once the outward flght was cancelled and brought forward a day, and once the return flight cancelled and moved back a day. Annoying when you've already booked the hotel and park tickets.
The Manchester flights are usually around 10am outward and 18:30ish coming back.
