Pros: There was nothing remarkable nor unremarkable about the flight. Everything worked as it should.
Cons: Poor reservation service from TAM.
I needed to change my return flight due to an emergency. Impossible to do so as the call center could not understand me, and I could not understand them, and my booking agent did not care. Eventually ascertained that the call center needed to submit an email request on my behalf and that I would hear by email between 24-72 hours later. Over one week later still not heard so gave up trying to change plans.
Also, could not pre-assign my seats on either outbound nor return leg.
As TAM is an American Airlines partner, rather use AA booking engine for the same routes.
