IT hamster training program?

I reckon Virgin trains the hamsters using VS1 (LHR/EWR) and VS2 (EWR/LHR) schedule changes. Why? Because those flights seem to move about so much it can only be hamsters practising for their final exams.

VS1 used to leave LHR around 1600. Then it moved to midday which was wonderful for us, morning in the CH, lunch on the flight, arrive mid afternoon in New York so we could manage an evening with the family before dropping asleep on our feet.

Booked our December 2016 flights in March. And the hamsters started their exams and re-scheduled the flight back to 1600.

Next lot of hamsters have now reached exam stage and the flight has moved another five minutes. And other exam candidates have moved VS2 similarly.

Is it just VS1 and VS2 they use or do they move other flights in this way?

Happens a lot, particularly on US routes. US-based airlines are notorious for it - I've had a DL flight changed 3 times before now.

Another day, another hamster's exam, so another schedule change appears for VS1. Except that it's the same schedule change as Saturday's change. Epic fail for today's hamster!
