It's the slow season, schools out. So, the drivers that usually work Tech are working Roanoke. I've driven during the day and it pays about what I make nights. Try it out and see if it's worth it to you.
IMO, too many drivers go out to the airport and just sit there all day.. but that's okay, more rides for the rest of us. lol!
Mornings have been fairly surprising for me. I've been driving for about a month and I'm surprised to see several people Uber to work every day. Nights have still been more profitable for me, but I think breaking it up into shifts throughout the day will be effective.
