I recently used Opodo to purchase tickets from Sydney Australia to New York return and I must say I was hessitant after reading all the negative reviews pertaining to their service. They offered the cheapest fare online and I saved $2500 for a family of 6. I could not believe the airfare price but took a gamble and my tickets were confirmed with Qantas within minutes. Also I noticed a discrepancy in the payment and sent them an email. Within 24 hours they replied and cleared up the problem. Lesson learned today. Don't read into people's negative reviews too much as it seems businesses like Opodo get misrepresented by these reviews, thereby altering your decision in pursue of a cheap airfare and possibly missing out.
