I just flew through LAX this past weekend with 2 bottles in my checked baggage and had no problem. However, I also did not volunteer the fact that there are wine in the bag, but they were packed snug.
Also, I heard the similar tale regarding breakage and leakage from a separate with SWA, and the CSR would not let me check the shipper box. I asked for a supervisor, and they wrapped the entire box in plastic bag.
The box arrived without a drop leaking.
