Use the find my gate feature on the flights phone app if available as the airport is a bit confusing

ANAFlew with FrontierMDW-PHXMar 2024

More organization and more staff, there was a lot from diferentes cities coming at the airport, so it was a mess because people don’t understand. Or don’t want to understand the instrucción of wait in their seats…. So more staff could be helpful..
