Here is something I do to minimize the high airport rates. Take a shuttle to another area, rental car lot, train stop, etc. and request Uber there. Saves on getting a driver that is not licensed to operate the airport pick up, reduced fare, etc. Downside is the extra time, but then again, if you keep getting canceled, it might be wash. One reason why fare tends to be high is because of airport pick up taxes that get added on in order for rideshare companies to operate in the airport, which goes to the rideshare companies.
