My mom is flying SCL-MIA-DFW-PHX later in the week. Having heard horror stories about clearing immigration at MIA, she chose a later connection to make sure she wouldn't misconnect. Assuming she arrives on time, she would like to connect and standby for earlier flights. The earlier MIA-DFW flight is looking promising, but the DFW-PHX leg is pretty full. If she were to make an earlier flight to DFW but not PHX, would she be entitled to use the AC in DFW?
As I read the rules, I suspect she only has access in MIA, but would like to confirm.
First and Business Class customers connecting on the same day of travel, or before 6am the following day, can access the lounge when travelling between an international long haul* and an international short haul or domestic flight (and vice-versa).
