Absolutely avoid this lot!! My son and his partner are currently travelling South America and are looking to change their flights. The airline are more than happy to do this at a reasonable cost, but couldn't make the change until they had my sons email. He gave the email and the airline said it was wrong, so he gave his partners email which was also incorrect. Apparently, when Kiwi booked with the airline they gave an email of their own and when my son asked for this email so he could relay back to the airline, Kiwi refused to give it to him, but they are more than happy for him to rebook the flights through them at 3 times the price. Be aware people!
