I have used the RTW flight team for 2 round the world trips and am currently towards the end of my second year away. Having researched costs I can say they offer the best value and most comprehensive flights packages around, without a doubt. They also have vast personal experiences travelling so you can trust that there are none better qualified to handle your round the world journey. Where the team really excel however is the free concierge service they provide throughout the duration of your ticket. I have changed my and my girlfriends dates and even routes multiple times, sometimes at very short notice. 9 times out of 10 these changes have not incurred a cost which would not be the case if you were dealing with the airline direct. These changes are done within 2-3 emails and are handled effortlessly. I have been very very impressed with the service I received so much so that I will not even bother researching other companies when booking flights again. In my opinion the RTW team are unrivalled with a service rooted in excellence.
