Hi Bealst1,
Thank you for your enquiry.
How far in advance, usually depends on the time of year, and the number of passengers,you might be wanting to book. During the cooler months, we would advise 2 to 3 weeks and during the warmer months, 3 to 4 weeks. That is not to say, there wouldn't be spaces available, if you tried to book within the advised time frame, as it's simply a guide, to help save disappointment. The larger your group the more in advance would be advised.
Our normal Premium Flight with breakfast included, is $448pp though we are currently running a Winter Special @ $388pp saving you $60, but this offer end 30th August 2015.
Do checkout our website for more details, the address can be found on the right hand side of our listing.
Please don't hesitate to ask if you have any further questions.
Kind Regards
Jenny
