VS401

Anybody any idea why VS401 has been consistently over an hour late taking off all this week and subsequently approximately 2 hours late arriving at LHR? Seems a bit strange than over an hour has been added to the flight every day?

the new schedule says it leaves Dubai at 11.10am, and not 10am

Is this perhaps because we change our clocks but Dubai doesn't. The flight times have been changed so it still arrives in Dubai at the same time. (I think, spring forward...)

It's just the summer schedule leaving at 11. I think it had to be changed to accommodate a little red arrival slot at LHR
