Flight Schedules change

I went to the travel agent to find out if there have been any Travel Warnings issued, nothing at this stage for Thailand! What I did find out was that our flight from Hong Kong to Bangkok had changed, we are leaving earlier, that gives us a bit more time to explore the city.  I then had an email informing me of updates to the flight out of Chiang Mai to Bangkok, the changes would have had desasterous consequences as we would not have enough time for an international check in. I emailed the Airline to find out if I could change to an earlier flight, they have changed us to fly out at 14:00, this will give us plenty of time to check in. Everthing is 'On Track' for the holiday!
