Great news! If you want to book scheduled flights, you can do so approximately 11 months in advance. If you book a fly-drive (for example on a Virgin Atlantic flight through Virgin Holidays) you can do so as soon as the brochure comes out. You could possibly even do that now.
The Brochure from virgin that goes up to December 2008 can be ordered from there web site.
We rang them last weekend for a quote for first two weeks in December 2008, which they gave us.
