Tracking Flights with Echo

Amazon Echo can now track flights via Kayak in Skills.  I tested in a realistic case.  Quite bumpy ride, you have to be too precise in your language.  Also does not match to what I really needed.  I needed to set up a monitor of a flight where Echo would periodically alert me as changes occur, and then the ability to modify the alert vocally.  Kayak says they will be improving the skill.
