More than S16?
What is more significant is that many services which might have been expected to be suspended through to end march are resuming over the next few weeks eg VY to Rome, TO to Orly, Eurowings to Cologne etc.
As far as I can see there is little/no increase over S16, the "extra 10 flights a week" are compared to the winter timetable and have all been on sale for months. It's a news article out of nothing... It's as if they are just trying to make random noise to stay relevant whilst the US route saga keeps dragging on... That's what we all want to see announced!
The other routes you mention are all year round anyway and have been operating during winter, although CGN is in the middle of a 6 week break.
