The only time I failed to find a ride to airport on Uber/Lyft was in Singapore at 4am when Uber just started their operation there. Other than that, no matter how odd the hour is, I was able to find a ride, albeit sometimes with longer wait time (10 min-ish). I personally think the risk is negligible, unless drivers leave them en masse.
