Hey, I went to Brazil in Feb about 1 1/2-2 weeks before Carnval, and stayed DURING carnaval, and left the last day in Feb...and last year, my ticket was only $660 (ish...i cna't remember for sure) And I also bought the Tam Brazil Pass which helped a lot too.....
But I also did notice that this year, the prices are more expensive than last, and I'm flying out around the same time...(but not for carnaval) I hate to say it...becuase I've been wishing for this day to come as soon as possible, but I almost wish my husband's interview was closer to carnaval, or during, so I could spend Carnaval in Rio..but that's what next year is for....oh well. I happy to bring him home on the 12th....safe and sound.
By the way, I researched literally EVERY airfare website worth researching, comparing prices INCLUDING taxes, both round trips and one ways, for tickets for Me (travel from Las Vegas to Rio) and for my husband (Recife to Rio, and Rio to Las Vegas) and my travel agent STILL beat the internet....you should check it out. It's worth it to get a quote at least.
http://www.brazilinvegas.com His name is Joao Augusto (Call him by either name) Tell him Andrea recommended you... I don't get anything for the recommendation.. I just think he gives great prices. This is the second time I'm using him. Plus, I always give him hell, and whine a lot about my itenerarys, so I feel I owe him a recommendation.
Good luck everyone!
