American Airlines changed flight without notification. Takes ZERO responsibility

American Airlines changed the originally booked and ticketed flight without notification. The subsequent flight was also delayed, the total delay time 8 hours. This forced purchasing of tickets on another airline on short notice at huge cost.

Upon enquiry it was stated that "Instead of a refund we they are subject to receive Trip Credit", only to walk it back 5 days later with "We have thoroughly checked the concern, and unfortunately, according to our system, the request for providing Trip credits has been declined."

If you want to fly an airline that takes accountability for their mess, DO NOT fly American Airlines.
