iOS 9 includes a flight data detector feature that’s very handy for frequent fliers. Your iPad can detect flight tracking numbers to give you a live preview of the flight details.
Wherever a flight number is written in an app like Messages, Mail or Notes, it will be underlined and yellow – much like detected phone numbers and emails. Tap the flight number and then tap Preview Flight when the option appears.
You’ll be shown an overview of information including departure and arrival times, current flight status and a map of the route. To return to what you were doing, tap anywhere outside of the informational pop-up to close the overlay.
