A little sharing for those interested to or already invested in Airlines stock, you may wonder why is AirAsia so unsafe and so many incidents. Check this website out : https://www.avherald.com

Aviation herald is a news website which report incidents, accidents, and crashes in aviation that make known to public. You could try to search AirAsia, Singapore (favourite of a lots), Qantas (World Safest), or any others airlines you wished to. You may found most of them has equal oreven more incidents than AirAsia/AAX. Due to the reason you couldn't park aircraft in midair like you park your car mid-road, aviation industry take any incidents (like engine breakdown or simply aircond not cold enough) very seriously. Some of incidents are simply technical or manmade while others are complex. FAA & EASA have very strict requirements to allow an aircraft to fly & as one of results, despite we saw commercial aircrafts have minimum 2 engines, aircrafts could fly with just 1 engine safely. Any extra than one is serve as redundancy. The aircraft could just proceed with the flight, turn back is just a precaution.
