Hi
First of all, I apologize in advance if this is in the wrong forum. There's so many categories that I seem to have gotten a bit lost sifting through it all
My question is regarding a summer flight to Japan. I will traveling from San Antonio to Chicago, then Chicago to Narita and Narita to Osaka Itami. I'm booking this itinerary thru All Nippon Airways (ANA). The first segment, san antonio to Chicago, is operated by United so I know I have to check in with United (there's no ANA counter anyway). Arriving in chicago, I'm not sure if I'd have to exit and check in thru ANA, since I don't think they're in the same terminal. Would I have to re-enter security, etc? I think I have 1 hr 45 min to connect.
Thanks
