1. As to the first scheduled flight, what was the ultimate delay in arriving at GWT? The fact of the reroute is unimportant. What is important is the time of your originally scheduled arrival and then your post-rebook scheduled arrival, e.g., the train's scheduled arrival at GWT. Under most circumstances, a tech delay will qualify for 261/2004 compensation, payable in a cash equivalent.

2. As to the second flight, you were notified more than 14 days in advance. Thus, there is no compensation due. You were, however, entitled to a reroute. Unless you have a proposal for a better reroute and AB refused that, the delay time is not really material, e.g., there was a flight with a 2-hour delay and space available, but AB refused you that flight.
