Which airlines are the safest?
It is difficult to specify which airlines are the safest in the world. Considering only the number of malfunctions and accidents does not cater for situations which are not in any way dependent from the staff nor the technical condition of the machine. Before being admitted to operation, every aircraft, regardless of the carrier, is subject to the same procedures at the airport. Identical mechanisms are checked and similar parameters are analysed. Technical inspections are also mandatory after the same time for every carrier.
Every now and then, tech magazines publish rankings of the safest airlines. Such rankings consider the conditions inside the aircraft, the age and technological advancement of the machine, or the quality of the meals. These are the categories in which low-cost airlines cannot compete with traditional carriers. However, the case is different in commissioned rankings concerning only low-cost airlines, where the mentioned New Zealand companies do appear and are ranked high.
