Captain - We did sign up for notifications....the only way we knew they changed the flight times was to go into our manage flights....I have not accepted the flight change yet....what happens if you don't hit that 'accept' button for your flight change...
I don't understand why they would add a new flight before our flight when we initially booked the flights we were the first flight in the morning....and the first change in times had the new flight leaving and arriving a half hour before our flight...now with the second time change the flights are an hour apart leaving and arriving....
