Uber is great for getting a lift right away on a friday night. If cab companies weren't run so dirt cheaply they would have a quality dispatch system like uber has.

However uber fails for the early am scheduled ride for things like plane rides. I can't depend that uber is possibly going to get me a lift. Taxis DO show up on time super early am.

Last two times I've flow early I've tried to get a uber, and both times failed to see a single one on the app. Told uber about it, they said "we dunno we had plenty of cars"
