BUSINESS CLASS : A somewhat mixed product consistency, with TAM business class providing older style seats in 2x2x2 layout, which recline to a near horizontal position. Sleep comfort is better than the angled lie-flat seats offered by many airlines, and a generous seat pitch is provided. Cushion comfort can be a little bumpy in the fully reclined position, but this can deliver a good sleep nevertheless. Score : 8/10

FIRST CLASS : High standard of comfort provided in these pod lie-flat bed seats. A good standard of privacy is delivered in the 1x2x1 layout, and seats are comfortable for both the sleep and relaxing positions. Score : 8/10
