We were ready 30 minutes earlier than necessary and we did not need the extra time. Oh, yes we did! On,no we didn't. Our flight is on Lufthansa Atl-Chicago-London. So we went to the domestic terminal only to be told we needed to be at the international terminal. 35 minutes later we arrived there only to be told we had to go to the domestic terminal. 35 minutes later - and now running late - we arrived back at domestic, checked our bags, raced through the airport. Our flight to Chicago is late! Now we are going to be tight in Chicago. Ain't traveling fun?!!
