Awesome Idea, haven't been able to really take advantage of it since most of my flights are direct from JFK anyway, but will definitely help in the future I imagine.
The "shop" and their customer service and response is total bs.
Ordered a t-shirt last Friday with 2-4 day shipping and I still haven't even received notification that it's gone out. My money was gone right away from my account of course. I emailed to ask about it and haven't gotten a response in 2 days. Honestly it's ridiculous. Should have read the reviews beforehand.
