Qantas pilots collectively were sufficiently myopic and arrogant that they isolated the Trojan Horse that was JQ as some sort of inferior scum (let's not talk to them on the crew bus) and this appalling approach is inevitably biting them on the bum now.
I, and many of my colleagues, have consistently made an effort to extract a "hello" out of JQ crew in terminals for years. That they look the other way in ~80% of cases has become a bit of a game now, so I hardly think that this is QF arrogance coming through. More like 'chip on the shoulder sheepishness' from the other side. For some reason, MEL seems to be the worst for this.
Still, I'll continue to say hi, exchanging courtesy to those who brave eye contact, and have a chuckle at those who choose to look the other way.
For some reason, the "QF/JQ/DJ/TT pilot" that people bitc# about on here seems to be a totally different person from the mate that they have known for years who works there. We really are not all that different.
