Shame we had to wait an hour after landing before we could disembark. With 11 hours notice and the flight landing on time, there is really no excuse for having no available gate for an hour

Unfortunately the in flight entertainment system was down so nobody had any entertainment for the entire flight. Other than this. No complaints.
