I don't know what it is but in basically every major airport I have struggled to get an uber/lyft. I expect at minimum one cancellation...

In many cities this is solved with the "Uber rank" system, where you simply get in the first car in line, give the driver a code, and then it loads up your journey. Fast and avoids any hassles with drivers rejecting your destination.

Trying to find a specific ride hail driver at the airport seems like a huge waste of time. Just go to the taxi stand.

Same. I assume it depends on the destination

Person wants to go somewhat far from airport? That's more time on this single ride and less time pocketing peak demand money
