I was on UA69 ARN-EWR on Dec 8th. I was fully expecting a fuel stop as the flight plan time was showing 9:20 when I checked FlightAware. Was surprised that no one mentioned the possibility at check in or when boarding - although I still expected a last minute diversion based on the headwinds and projected flight time. But it didn't happen. Guess I got lucky as it looks like day before and day after diverted.

The flight was not that full - probably about 1/2 full in Economy as far as I could tell, so maybe they were able to load more fuel??
