Expertflyer Voice, can you tell me precisely how often the "saved flight alerts" are run? Once a day, twice a day or more often? Can you tell me exactly the times your system usually runs the saved flight alerts created by your customers?

I tried to test the frequency the "save flight alerts" are run, for example, I tried to set up an alert for a NZ flight "I" business award seat on NZ101(AKL-SYD) on 9/26, it already had 3 "I" seats available before I set the alert, but after I set the alert for that flight, a notification was sent to my email address only after 22 hours! The 3"I" award seats has been there within the 22 hours and nobody has been taking away the 3 seats, so why the system did not send the email notification much earlier? You know sometimes 22 hours make a lot of difference. I hope you can answer the doubts I have. Thanks!
