what could this have been??

I am afraid that this is going to be somewhat thin on detail but a plane flew over today after taking off on 34L. I THINK the time was about 11.30am, but I could be completley out on that. Again I THINK it was a 767. It had 2 tone cheatlines (one light blue, one a darker blue). The cheatlines curved up onto the tail and became much wider. There was blue writing above the windows forward of the wings which I couldn't really read, except the first letter was an 'A' - it looked a bit like a stylised "ATA", but I really couldn't say what it was. I've checked the Acars on 16R.com (such a great resource, thanks Grahame) and the departures on the Sydney Airport website, but nothing looks like it could be a match. Any charter movements today??? Thank you
