The reason why alert was ranging(or flickering) must be investigated. Especilly, Singapore Airline is famous as one of the safest airline companies. If the company skip it, its reputation will be plumetting.
When it comes to the airline company whose headquarter is located in the neighboring country to Singapore, Malaysia Airline lost trust after disappearance of MH370. When I was looking for flights to Kota Kinabalu from Osaka(Kansai), Malaysian airflights were listed as vacant seats despite it was during Golden Week(long holidays in Japan). It shows how big the effect of the accident was!
