VS9 / 10 seems to be running with a lot of gaps in the schedule at the moment. Last week this was down to the snow in New York, but VS10 luckily ran on Thursday when I was booked on it, albeit with a 2.5 hour delay. Is this a flight that often gets pulled this time of the year due to light loads?
Lots of flights have been suffering light loads of late and many have been cancelled /amalgamated as a result (these have been publicised well in advance). The weather has also been having a significant effect in the past few weeks - my flight on the VS10 (26.1.11 ) was cancelled due to the adverse weather conditions (lots of snow in NY). I don't think the weekday VS 9/10 is one that generally gets pulled unless it's due to inclement weather.
