Codes people book by mistake

Code What it actually is
CGH Congonhas, in the middle of São Paulo. Domestic only, and a much shorter runway.

The other code, SBGR

Every airport has two codes. The three-letter IATA code, GRU, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, SBGR, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why SBGR looks nothing like GRU.
