Arriving in Dallas from Puerto Vallarta on March 8 at 15:50 on American Airlines. Departing Dallas on March 8 at 17:15 on American Airlines. Will this be enough time (85 minutes) to clear customs and make our connection to MPLS. We have never flown through Dallas before, and are not familiar with the airport (size, terminals, etc.). Any advice, or suggestions woiuld be greatly appreciated. Thanks.
