Asked for water before dinner was served, didn’t get it. Dinner served but no drinks was asked or served with dinner. When asked if I wanted my seat made for bedtime, asked for water again. This time I got it. Filled the breakfast form but was still asked what I wanted. Comparing this experience with Fiji air flight from LA to Melbourne. Worse was missing my flight connection to Baltimore since Fiji air opted to wait for a passenger that couldn’t pass security. Instead of leaving at 9:40 pm, we left at 11. So spent overnight at a hotel for next day’s flight. Another expense!
