I am flying from bombay to charlotte in july...my itenary is Bombay-Frankfurt-chicago-charlotte.
Bombay to chicago is entirely on Lufthansa and chicago to Charlotte is on United airlines....
At Chicago the Lufthansa flight arrives at terminal 5 and the next domestic flight is at terminal 1..I wanted to know if i have to carry my checked in baggage from terminal 5 to terminal 1 on my own or will it be transfered by airport authorities after the customs check at terminal 5...

PS:I have almost 4 hours between the 2 connecting flights...
