I have a flight connection of 1hr 21 mins at Chicago from LHR inbound on UA 959 to get outbound Las Vegas flight UA110, is this enough time to clear customs, immigration, security & change terminals, and hope the baggage makes it as well? The next flight will be the next day am. My last trip into Atlanta from LHR had to go thru security,immigration & customs, just to get out of the terminal.
