On July 14, I’ve got a 6:00am flight to Chicago O’Hare, so I was thinking of getting an Uber to SFO Terminal 3 (United Airlines terminal) at 4:00am so I can arrive at the terminal at about 4:30am. Will I be able to get an Uber at 4:00am or should I reserve one so I’ll be guaranteed a driver? Any help is much appreciated!

I’m not sure this is the correct subreddit for this, but I would like some opinions. I’m currently in Thessaloniki, Greece and reserved a rental car for tomorrow, which will be an Opel Crossland. Is it a good car or should I get a different rental car?
