Avoid this company. I bought the ticket well in advance but for the second time, they are trying to change the trip schedule. They want me to fly one day earlier on my return from Brazil having to stay for one night in Sao Paulo before the long-haul flight. UNACCEPTABLE. After many emails the only response I get is that nothing can be done, and if I am not happy with the change I should cancel and get the refund. The problem is the same ticket will cost 50% more if I need to buy it again. After a quick search, there is a flight that I could be put in with my family if the change is really necessary, but Vayama is also refusing to do it.
