anyone understand the flight bookings system....(local and OS) through 'go to gate.com' (apparently a Swedish booking.com) cheaper then going direct to Virgin au etc, I guess this is pre purchased tickets etc.. in the past Ive purchased direct form the airlines but lately the search engines through web jett, cheap flights etc, etc seem to push to multiple booking agencies and I'm wondering how you tell if they are legit and not just those with the best SEO. any help appreciated.
