I think Uber is vastly superior as compared to taxi's in Boston as maybe compared to other cities. I've used it to Logan multiple times with no issues.
Pick up at Logan is a little wonkier because they need livery plates (I think), but drop off is as easy as if a friend did it.
Highly suggested. And yes they are serious about the no tipping thing.
If it's your first time using it, you get $20 off your first usage. If you know anyone else who uses Uber, they can give you a code. Or I can give you mine
The person whose code you use will also get $20 off their next trip.
