We had a great conversation with our limo driver in November. He told us he drives for Uber when he is not doing work for the limo company. We asked him pretty much the same question and he told us it can be hard to get a Uber to drive that because they normally have to get back to where they came from, think PC. If they picked you up at the port chances are they live and drive in that area so once they drop you off at the airport either they need to fetch a fare for the way back, which they often can't do, or they lose money in the hour it takes them to get back home. Hope I explained that all right.
