Ken's got a point about media selectivity. Brisbane had several overnight diversions the other day ......... The local media wrote it up as '200 Qantas passengers stranded in Brisbane' with nary a mention of the other carriers.
If I may butt as a pom: it's the same the world over. Even if the whole of LHR has gone to hell in a handcart (which it does every time it snows) the UK media will find and lead with the stranded BA passengers story. We/you are the local tall poppies I guess, so it goes with the territory (doesn't mean it's right though).
