My own airline was a Boeing early customer, operating 707, 717, 727, 737, 747, 767, 787. Recently we ordered the A320/321 instead of the Max. We ordered the A220 and the A350 too. Boeing bet the company with the 787 and lost. Its going to take it a few more years to fall down though.
Sad to contemplate. More than any other maker, Boeing aircraft opened up the world.
