Thanks for your response. I don't understand bolded part. Can you explain?
I also went through an old thread that detailed the difference in term language. So, I am happy. Just wanted to use the best card with travel protections and still get the free checked. I don't mind possibly sitting in the middle. I am saving $300 bucks (in total) which I can use for a fancier experience when I arrive.
