I don't get it. I received a ping from outside a rental car company, right on the street up from the lot. In thinking about this, I may have been physically the closest uberx to him, as I was in a parking space at the edge of the lot closest to the rental car companies. I have yet to receive a bona fide ping from an arriving passenger where the pick up can be made at arrivals or the short term lot, since uber made their 9/1 announcement.
And at DCA, yesterday, 2d time this happened, I dropped off a pax and immediately received a ping to pick up a pax also at DCA.
That is what probably is happening to me too. 5am ashburn is dead for drivers. My problem is, I am at airport, I don't want to drive around. I want airport pickups.
On your second note, I have been fairly successful at getting pings. Sometimes the waits are longer then I would like. 45-1hour. But they payoff has been pretty good. Most rides are a good distance and out me near city for rest of day...
glitch in the system. Most of the time, it's the other way around. You sit in the waiting lot for an hr and start getting pings from chantilly/sterling and get kicked off for not accepting them. There are times if you are driving around sterling/reston area, you will get pings from the airport, and really start scratching your head when u drive by a lot full of uber drivers as u leave the airport. This surprisingly happens alot.
