Question: how far in advance can you book jetstar flights?
Answer: Veteran Member. Today you can book JQi as fa in advance as Sept 16th 2011 and Sept 15th for domestic. That tells me that booking for JQ are available at ~11 months out or 335 days. Contrast the with Qantas who are today sellng seats as late as Oct 3rd or 353 days in advance.
