cost to divert
way back in 2001, i was told that any diversion would add up to a minimum of 3000 pounds sterling. from a reliable director of operations for an unnamed airline based in brussels with a slight red tint. what with airport landing fees which might be higher for unscheduled flights, extra ATC charges, supply/demand fuel pricing factors etc.
i have asked present airline and they seem to think that we don't need to know that information. treat us like mushrooms they do.
D.I.Y. airlines these days
