I'm flying YYC-DFW-MIA-GCM in a month, but it was almost $1000 less to buy an itinerary that involves a 9-hr layover in DFW, the last flight DFW-MIA, and an overnight in MIA before heading home.
Since I arrive in DFW at 11:19 and there are two flights DFW-MIA that would get me to MIA before the 20:03 MIA-GCM, how likely am I to get an Admirals Lounge agent to bump up my itinerary being a Platinum so I can make that flight and get in the same day? Is there a minimum connection time that would prevent me from being able to fly on the 12:49 DFW-MIA?
