I haven't actually seen a new look to Google Flights, but my scripts in the last few days have been occasionally failing because Google seems to be testing different layouts.

They seem to be trying to make the page look a bit more like Kayak / Momondo by displaying what they consider to be the "Best" flights by default. The odd thing is I have the sort set to "Price" which is overriding the "Best" option and probably making the page look like the "Cheapest" option.
