Exactly, different than the 3 radio taxi companies with booths inside the arrivals area and is a regular yellow cab.

Last week the flat rates to Copa from GIG were R$50 (Band 1) and R$60 (Band 2). R$3 was added on for my two pieces of luggage. I have paid more than that going to/from GIG on the meter so I feel it offers good value particularly if there's going to be some traffic. Also offers some assurance to a first time visitor that they're not going to be overcharged by a rogue driver that they hail outside.

Never had any issues with these guys. Funnily enough I was at T2 heading to EZE last Sunday and an Aerocoop taxista came up to me and said he'd brought me from GIG earlier in the year. Named the street in Copa and even remembered it was my friend's apartment which I thought was pretty impressive given the no. of customers they have.
