I see that this morning's partial reopening of Gatwick (limited services etc) coincides with National Rail/Southern finally having got their act together to also begin operating train service to the airport as of around 4am this morning on a half hourly basis.
Call me cynical if you like but it would appear that the Gatwick management seemed to think there was little point in reopening the airport if the rail service connection also did not exist.
Its also interesting to speculate why it is that the only flight Easyjet seems to be managing to operate today is the one to Ivalo. Is this because that particular pilot is used to landing on and taking off from an ice covered runway.
