Can you cancel the entire trip to Bangkok? Do you need to be at Bangkok in next a day or two? I think one of options is to cancel the entire trip and plan the trip again some other time.

I was at Tokyo during last month's Typhoon no. 15. A day after typhoon NRT was pretty much back to usual in terms of flight schedule, but catering could not have supply delivered. Flights had small plastic plate of meal, no bread, no salad, no sweet, nothing else. It was same in First and Business. Yes, First and Business class passengers got served same small plastic plate meal served in economy and that was it.
