As the time schedule has just changed and the passenger received msg from the company this morning. The problem is mainly about timing that passenger planed for their business. Changing flight schedule can effects a lot, thinking about domino effect and you will see many trouble thing will be affected in follow.
The most important thing that airline company must be concern is time to notice or inform passenger in any changing of all circumstances more than 48hrs. Then passenger will have time in advance to re-manage their timetable. Thank you.
