Found it a little odd that BOS is on this list as UberX remains banned from picking up at terminals unless an UberX driver happens to have a livery plate, resulting in long waits for pickups there. Does Uber really want to make the wait times for a ride out of there even worse than they are now?
FWIW, there is currently a workaround for the ridesharing restrictions involving taking the Massport shuttle bus to the rental car center or the Blue Line station, though its not clear whether this promotion would apply to such pickups. The terms simply state "you must enter the airport name in the pick-up location in the Uber app when requesting your rides," which leaves ambiguity as to whether a non-terminal location on airport property would be fair game...
