Just had my first Jetdeal cancelled (was previously 3/3), after it had been confirmed about 12 hours in advance. Unfortunately, I had planned on using the Jetdeal for my outbound flight and a Jetshuttle for my return.
Despite cancelling the Jetdeal after confirming it, Jetsmarter won't waive the $1000 fee to cancel my Jetshuttle flight. I get that this is technically within the terms and conditions, but it's pretty customer unfriendly.
I had previously been really impressed with my entire Jetsmarter experience - legitimately had no complaints whatsoever. This seemingly small thing is pretty frustrating, and I just don't get the point (other than to try to take a few bucks out of my pocket).
