Hi there. So anxious. Have not travelled for over seven years and I'd like to know I can get to terminal 7 from 8 without exiting the building. I had a bad experience when I changed flight from japan airline to American airline; I had to grab a taxi outside and almost gotten frostbite in a -8 degree weather. I only had a flimsy sweater. Please help and advise. Many thanks!
