Before it suffered the deadliest crash in South Korea's history, budget airline Jeju Air was moving fast: racking up record passenger numbers and flying its aircraft more than domestic rivals and many of its global peers,

In fact, only Saudi Arabian LCC Air Arabia bested Jeju's utilization rate last year at 12.5 daily hours. Data from aviation analytics firm Cirium shows that Jeju was flying its planes an average 11.6 hours per day - this is considerably higher than the likes of Ryanair (9.3 hours), AirAsia (9 hours) and VietJet (10 hours).

After overcoming pariah status at the end of the last century, South Korea must learn what caused the catastrophe on Dec. 29 and what lessons to draw from it.

Shares of South Korean budget carrier Jeju Air hit their lowest on record on Monday, after the deadliest air crash in the country killed 179 people.

South Korean investigators said Friday they expected to find more human remains as they began lifting the wreckage of the Jeju Air jet that crashed on landing last weekend killing all but two of the 181 passengers and crew aboard.

The aftermath of the Jeju Air crash at Muan International Airport in Muan County, South Jeolla Province, has dealt a severe blow to Vietnamese tourist destinations popular with South Koreans, leading to a significant drop in travelers.

Da Nang and Phu Quoc have seen a sharp decline in South Korean tourist arrivals as a fear of flying has taken hold following the Jeju Air crash.
