Getting us back on topic again. SLC-NRT sounds like a very good addition. Another strong rumor is BOS-NRT. BOS has been screaming for service to Japan. I think DL will be first to the plate.
there is a reason no one is doing BOS-NRT, can you guess why?? B/C it doesn't make money!!! Have at it, you will lose your arse, just like SLC-NRT... Most airlines tend to utilize a/c on their most profitable routes, so this wouldn't seem like a good idea.
