Any change in tone or difficulty in taking the note may be an indication of a leak. Leaks may be caused by problems with pads and with the regulations between keys as well. Then, if any is detected, it's time for taking the flute to a technician for proper repair.
Is it hard to play high notes on flute?
When playing high notes on a flute, you first have to be committed to playing them! It's very similar to an athlete going over the pole vault bar. It just wouldn't work to give half-an-effort. Like the athlete, flutists fall short of the goal, have fuzzy tone and accidentally play an undertone.
Why are my high notes airy flute?
Feel the air hitting the lips in the inside and shape them to reduce the air flow. The trick is not to use the throat to reduce the air flow, just the lips. And, of course, when playing you don't have to exhale in full force, specially with the first octave.
