I have a stopover question, hopefully its allowed in this thread. I am flying business from ORD NRT to BOM and have a 20 hr layover in NRT on April 7th. What are my options since things are still so fluid due to Covid. Are lounges open ? Would I able to use them in the night or do I have to book a hotel ? Can I step out of the airport or I have to spend those 20 hrs in the airport? Any directions would be greatly appreciated.
