Not sure where to send this suggestion to, so hopefully the community is the right place.
We accidentally bought a super saver class upgrade, thinking it was a ticket. We luckily didn’t get fined. Admittedly, we should have read the information available more thoroughly, but I think it would be a great improvement to not allow someone to buy an upgrade without also buying a ticket.
As a software developer I think the best designs are those that give the user guard rails. In this instance, a guard rail was needed.
Thanks!
