Uber ($UBER@US) announced today that customers can now book a ride up to 30 days in advance. And travelers who choose the more expensive Uber Black or Uber Black SUV options can also put their flight information into the app to automatically adjust a reservation if the flight is early or delayed. Uber said drivers for those reservations would wait up to 60 minutes at no additional cost. The airport booking option will appear in the Uber app under the Reserve tab starting today. The features are rolling out to riders at more than 20 airports across the U.S.
