Flight overall good. Smaller regional jet and plane was full/crowded. Carry-on bag had to be gate-checked due to lack of space, but was available promptly on arrival. Be prepared for a long walk from domestic arrival gate to international departures area, but CLT has many moving walkways to help the process and allow older travelers some rest, or in my case to speed-up the process. Routes are well marked. Lufthansa staff at departure gate helpful and efficient.
