Welcome to FT.

I would have agree with the others here...

I know it is frustrating to be stuck in traffic and miss your flight... if you travel enough, it is bound to happen.

Even though your original flight you were scheduled to take was diverted, you are not (IMO) entitled to compensation for that. In fact, I think you were lucky to get on a later flight that day for just a small change fee, compared to what you could have been charged.

I really do doubt that the flight diversion was known the staff in NY at the time they rebooked you, but even if they had known that, you weren't on the flight anyway, so I am not sure why that really matters here.

My advice to you, if to count this one as a series of events that lead to an inconvience, but it appears that they did what they could to help you here, as it really could have been a lot more expensive and compounded the misery even more.

Hope you have a better experience next time!
