Please don’t let stuff in the news get in the way of enjoying your life as hard as that can be for people with a fear of flying.
I have been flying for 40 years, I wouldn’t hesitate, not for one second, to fly on any Boeing aircraft.
I would would avoid certain airlines that operate Airbus ( other countries….even then, very few ) more than worrying about whether your next flight will be in any Boeing.
I am approaching the end of my career ( 22 years on Airbus ) , and might be switching over to the B777 ( best long haul flying at my airline….most productive ).
Pilots love the B777, and 787 ( not the 737 but that’s only because of the smaller cockpit versus A320 ) at my airline.
Enjoy life, please do not worry about stuff like that.
The media thrive on scaring people.
