Having re-read your earlier post, there's probably little more I can elaborate on, it's just a matter of opinion: I've found J service on LA pretty poor (both against the benchmark of other OW carriers and per se). The cabin crews are sullen to the point of cold (though the new uniforms are groovy), the airline consistently under-caters and I've never flown with anyone else in business where I've had to ask for more than one drink on a 5-hour flight.

Contrast this with a generally good (for Y) standard of service I've experienced on the other side of the curtain when flying LA and I start wondering what the airline believes makes its J offer distinct from Economy, other than the fact that the people up front have paid more for their ticket?

Eastbay1K, I gather your experience of LA has been altogether more positive, which is great. I, however, believe them to be a shabby outfit. Alas my loyalty to OW carriers and LA's near-monopoly gives me few other choices when in South America.
