Does anyone have an insight into why/how often the 332 is substituted with a 333 on the CLT-DUB route? It’s scheduled as a 332, but every once and awhile (last night for example) it’s a 333. I am booked on this flight in July in PE and am hoping this doesn’t happen to me. Also, what would AA do with a PE ticket holder if the 333 is subbed in the day of? Thanks!
