United Airlines CEO Oscar Munoz has told CNBC that he will not assume that travellers will feel comfortable on Boeing 737 Max jets, when the aircraft returns to the air.
Munoz said: "We will be incredibly communicative to all our customers and very transparent when that aircraft comes back.
"The first and foremost objective is to not assume everyone will want to fly, or assume everyone will get over it."
The Boeing 737 Max jets were grounded worldwide in March following two of them being involved in deadly crashes less than five months apart. Boeing has since attempted to fix issues with what has been pointed out as the main catalyst to the crashes.
Munoz, speaking at New York's LaGuardia airport, where the carrier is opening up a new terminal, stated that United Airlines will wait until "everyone agrees" the Max is safe to bring back.
He added: "We're going to do this in a safe manner. The first and foremost objective is to not assume everyone will want to fly, or assume everyone will get over it."
