Air fares vary a lot throughout the year: prices are higher in July, August and mid-December to Christmas Day. Getting a seat during the Carnival (Feb-March) can be difficult.
Apart from discounted fares, it's worth checking directly with the airlines. Use the internet to that effect; it's easy to get competitive fares during the low season, as long as your stay involves at least seven days.
Flights from the US and Canada
Direct flights leave from Toronto, New York, Orlando, Washington, Atlanta, Chicago, Dallas, Houston, Los Angeles, Miami, Newark.
Brazilian carrier: TAM
North American carriers: American, Air Canada, Continental, Delta and United
Others: Japan Airlines and Korean Air.
Most flights go to either Rio de Janeiro or Sao Paulo, but TAM offers options from Miami to Manaus, Belem, Belo Horizonte, Recife and Salvador (Bahia).
American also offer flights from Miami to Belo Horizonte, while Delta offers flights from Atlanta to Fortaleza, Manaus and Recife.
Flights from Europe
There are many direct flights from several European cities.
TAM (Brazilian carrier) and TAP (Portuguese carrier) are the best carriers for flights involving destinations like Salvador, Fortaleza, Recife, Natal, Belo Horizonte or Brasilia.
TAM is the best bet for a direct flight Manaus or Belem in the Amazon (though it's unlikely to be cheaper than a flight to Rio or Sao Paulo with a connection to Manaus).
But there are many other airliners offering flights to Rio and Sao Paulo: British Airways, Air France (via Paris), Iberia (via Madrid), Lufthansa (via Frankfurt), Alitalia (via Milan), KLM (via Amsterdam) and Swiss Airlines (via Zurich).
Do not forget, anyway: flying with TAP (or TAM) broadens your options, namely to Bahia, Fortaleza and the Northeast in general.
Flights from Australia and New Zealand
Consider the Aerolineas Argentinas and the LAN Chile.
From Australia, flights to Brazil leave from Sydney with scale via Auckland to Buenos Aires and from there to Florianopolis, Porto Alegre, Rio and Sao Paulo.
LAN Chile has a direct flight via Auckland to Santiago, with direct connections to Rio and Sao Paulo.
Brazil has a multitude of options. Rio de Janeiro, Manaus, Iguassu Falls, Florianopolis and Salvador da Bahia are all very different destinations. They offer different "Brazils".
And that's where the Brazilian Air Pass enters: it allows huge savings in the internal Brazilian air-flights.
One Brazilian Air Pass are valid for stays between 3 days (minimum) and 21 days (including the day of departure) and are only available to foreigners and Brazilians residing abroad.
Two Brazilian Air Passes are valid for flights between the brazilian airports served by the carrier to whom you buy the pass.

TRANSFERS AND TAXIS
Most Brazilian hotels don't run shuttles.
In most cases the absence of a shuttle isn't really important. You can simply take a taxi at the airport, a bus or other means of transportation.
Regular, metered taxis - identified by roof lights - can be easily found on the airports.
Brazilian taxi fares are affordable and the service is normally efficient and professional. Fares can be shown by the meter, but more often are listed on a chart taped to the rear side window of the vehicle.
Abundant at the airports and the urban areas, taxis are difficult to obtain at certain hours and zones in cities as Sao Paulo or Rio de Janeiro. In these places, radio taxis (cabs) are a good and cheaper alternative. They can be found at airports or summoned by phone. For a cab-taxi in Rio the Janeiro call: 270-1442; in Sao Paulo: 0800-106688; in Brazilia: 325-3030; in Belo Horizonte: 0800-3350550.
Contacts at the airport are often made by the driver or someone else holding a sign with the name of the people involved. The main airports have information centres that can provide free booklets, city maps and local information. If you need local information, look for these touristic offices at the arrival airport.
