Not bothered
Not bothered, I approached the BA ticket desk explained in a loud voice how I had been given the wrong instructions and blah blah, missed , queue blah…
BA being BA this was not problematic, new tickets we issued without establishment of blame/consultations/rebuffals/attempts to make you buy more tickets etc.
All very civilized ´n that. Like Yorkshire Tea, Tea the way it used to be but for flights.
