I've been trying to use UA to search and it feels like every single LHG flight I'm looking at has some married segment logic, moreso that when I was looking earlier this year. Does anyone know if the same married segment rules would apply across all partners if I try to call and book through AP?

Also, is there another reliable site for *A availability that extends to Aug 2024, similar to AP? UA search calendar is about 2.5weeks behind
