Hailing a ride from the airport is often a headache — ask anyone who's navigated a maze-like terminal just to get to the pickup area. The journey may soon be less daunting, however. Uber is introducing a few updates that can streamline trips to and from airports. Most notably, you'll get walking directions for the pickup location, and ETAs for baggage claim. You can hustle if you need a ride quickly, or take your time collecting your bags.
