If you are traveling to Brazil, cheap flight (Buzios) options are not always easy to come by but they are out there! If you look carefully enough you can find a cheap flight to Buzios Brazil, but it depends entirely on where you are coming from. Unfortunately, if you are coming from anywhere in Europe you can probably forget about finding incredibly cheap Buzios flights, but if you book well in advance there is a good chance you can find flights for under400.
All of the airports in Rio de Janeiro use the airport code RIO, but Rio de Janeiro international airport uses the code GIG. This can be a little confusing to some, so make sure you clear up with your travel agent exactly which airport you are booking for, because the price differences can be huge for tickets to different airports.

Unfortunately if you are looking for discounted flights/airfares, Buzios is not the place to go during the November - February season. Flights from anywhere in Europe are likely to cost you around 600, and flights from anywhere in the US can cost well over $1,000 even if you fly coach. This is not even including Buzios airport rental cars, so you should definitely budget well for this. Lufthansa and TAM Brazilian airlines usually offer the lowest prices on Buzios flights around this time of year.
If you're going to Brazil, cheap flight (Buzios) options are really only available in the off-season when it is a little more rainy. However, the price difference is usually not very great so if you want to be in Buzios for the carnival it is well worth the extra $100 that Buzios flights will cost you during the peak season.
Brazil cheap flights, Buzios accommodation and transportation between the airport and your hotel are usually something you pay a bit of money for, but booking advance is the key. The price drops by about $50-$100 for every month in advance you book, so if you are planning on being in Buzios for the carnival you should probably get out your calendar and make plans for next year because you are very unlikely to find Brazil cheap flights (Buzios or anywhere near it) during the busy season.
