The airline company relied on SMS and email to notify passengers about flight changes. It worked — sometimes. Messages got delayed, buried in inboxes, or simply ignored. When delays stretched into hours or flights were pushed to the next day, the call center lit up with confused passengers. Staff couldn’t keep up with the flood of questions.
IVR that actually calmed the storm
This time, the team didn’t waste hours on manual dialing. With Callo, they recorded a quick message right on the platform in their own voice, explaining the cancellation. In minutes, the message went out to every passenger, paired with a simple IVR menu:
— Hello, your flight SW 452 from New York to Chicago is delayed by 3 hours due to weather. Press 1 if you’ll wait for the new departure,
or press 2 if you’d like a refund or rebooking.
No jammed phone lines, no chaos. Just clear, instant communication at scale, with passengers’ answers logged automatically for follow-up.
SMS is fine, but when your flight changes by hours, people need to hear a voice. Callo gave us that reach — fast, reliable, and at scale
