DUBAI: Flydubai remains confident in the airworthiness of its Boeing 737 planes, an airline spokeswoman said on Monday, a day after an Ethiopian Airlines 737 MAX 8 crashed. Flydubai operates a fleet of Boeing 737 aircraft, including the MAX 8. China’s aviation regulator, as well as Ethiopian Airlines and Cayman Airways, have grounded their 737 MAX 8 jets. “We are monitoring the situation and continue to be in touch with Boeing,” the spokeswoman said. “The safety of our passengers and crew is our first priority.” A crash of an Ethiopian Airlines 737 Max 8 killed 157 people Sunday. A Lion Air model of the same plane crashed in Indonesia in October, killing 189 people. Boeing has said it is not issuing new guidance to airlines about its 737 Max 8 aircraft after the fatal crash on Sunday.
