Over the past few months, we have been working on a research project shopping for round the world (RTW) flights. We came up with three different fictional RTW itineraries – ranging from a super simple, 4-leg trip through major hub cities to a super complicated, 18-leg journey. We then took those three itineraries, posed as customers, and shopped them among 8 different companies selling RTW plane tickets. We shopped all three itineraries leaving from New York, London, and Sydney. Below you can find the rankings of each company we shopped based on our experience posing as customers. Click on each one to read an in depth review and to leave one of your own.
