To LAX there is LY, and for me it's actually a downgrade since most of my flights to the US are to Florida (mostly MIA but sometimes MCO), or to LAX (however then I take the direct flight).

The fact that LY's US partner doesn't have business/first class, will, in my opinion, cause many flyers to prefer other airlines (unless LY will sell their tickets for cheaper prices than other US competitors), and that's a shame. I don't want to fly in coach after a long transatlantic flight, unless it's a one hour flight.
