Honestly, even if Boeing, the FAA, the airlines who own or have ordered the 737 Max, and everyone else gets this show back on the road, there is a much bigger problem.
Passengers! Those whom I have spoken to here at Dublin Airport who travel regularly and know the score, have without exception said there is no way they will fly on a Max. Those who are not fully aware, the occasional pax who fly once a year on holiday, will be heavily influenced by the media. The media in turn will report what they wish, regardless of the facts, and the news will not be good. The
PR teams for Boeing, and indeed IAG, FR, AA etc etc must be having some sleepless nights.......
