United Airlines is testing a new feature that provides more detailed alerts to delayed travelers at Bush Intercontinental Airport in Houston. Instead of simply telling customers that their plane is delayed due to weather, United is beta testing mobile alerts that provide fuller descriptions on how the weather is affecting flights. It also provides information on flights that are delayed for other reasons, such as maintenance. The program is called Every Flight Has a Story, and it will send alerts about delays of more than an hour via text, email and the airline’s mobile app. Mike Erbeck, who oversees United’s traffic in and out of the airport, said that the initiative was about being as transparent as possible with respect to travelers’ time. If travelers get additional details, he said, they can decide whether they want to wait it out, take a different flight or cancel a business meeting. The alert system is being tested in Houston and Chicago.
