Watched episode 1 of "A very British airline" and was stunned at the lost opportunities - almost like "Motorway cops at FL310", but without the humanity.
Their cabin training regime comes across as inept, petty and focussed more on appearance that content - not knowing that a cabin config is 3-4-3 is relevant on the aircraft (unless you're a Res or CKI agent), not a reason for dismissal but not weeding out someone who who hasn't a clue how to talk to a customer - let alone a foreign one - is irresponsible. (You can train skills, you can't train culture)
They lost the chance to really show the complexity and knock-on impacts of maintenance delays on schedules, they managed to pump some more fuel into the class war fire with "His ticket costs more than my annual salary" and the whole thing came across as utterly trite.
Look at "The Tube" to see how it can be done....
