BLAME IT ON THE BULLY
Its true that Biman do not have good reputation due to mismanagement lately. So after hearing the news that a Bangladesh Biman flight was banned entry into US over safety issues, it was expected that people would bully Biman.
But until now its safety record is not that bad. People paid no heed to Biman's claim that the aircraft was okayed for landing in New York and the US authorities had no right to refuse it to land.
Now the US State Department has apologized to Bangladesh's national carrier, Biman saying that it was FAA's mistake.
I think Biman should seek compensation for the financial losses it suffered as stated by them earlier. And the US authorities should apologize to the 257 passengers too for causing them much trouble.
