Hi, everyone...
Thanks for the replies... and yes, I as 3+ MM know to check my flights. But I've always received notice of the changes. Also, I've never had a situation where the revised flight landed 4 hours after the next flight is scheduled to leave. To add the the frustration, the AA Agent started blaming/lecturing me about it.

After this experience, I checked all my flights for the rest of the year... and had a similar situation going to Hawaii in September. Flight departure time of first flight changed, so flight is scheduled to land 2 minutes after connecting flight departs. I had to move the flights up a day to take care of it.

I've not flown much since March of 2016 due to some career moves... this seems a lot worse than it was then... or have I just forgotten?
