Hmm. Last sukkos I checked 3x70 on US (US*G). After all the bags were checked the agent made a comment like "you know you really got to watch the weight on the bags". So I said that I thought it was 3x70, he said they are told 3x50 but on the US website it says 3x70 (never saw it there). I'm not sure what happened there, or if the fact that my status is US made a diff, but I find if you go to FC check in, you usually have minimal hassle
