I'll be doing an early year MR to NRT this month so as a first-time Asia traveller, this thread is very useful. I am coming into NRT on AA175 from DFW and then departing NRT on AA154 to ORD. I have roughly 4 hours at NRT, and my lounge strategy is to first go to the AC to have a shower, and then to head to the JL F lounge to spend the rest of my time there. From what I have read, the AC showers are the best at NRT. For those of you that are NRT experts, does my lounge strategy make sense?
