If being able to pick an acceptable seat ends up costing more than this, I'll be firmly in the territory of just price shopping between the other US airlines and picking whoever has the best price for the route. Admittedly, as someone who flies alone the vast majority of the time, this system worked well for me without much overhead. I can understand how families might be relieved at being able to reserve seats all next to each other as the cost of early bird for say 4 people would really add up. I guess I'll just be enjoying my current setup while I can and then move forward without any sort of loyalty.

We discovered a Local Privilege Escalation (from any user to root) in polkit's pkexec, a SUID-root program that is installed by default on every major Linux distribution:
"Polkit (formerly PolicyKit) is a component for controlling system-wide privileges in Unix-like operating systems. It provides an organized way for non-privileged processes to communicate with privileged ones. [...] It is also possible to use polkit to execute commands with elevated privileges using the command pkexec followed by the command intended to be executed (with root permission)." (Wikipedia)
This vulnerability is an attacker's dream come true:
- pkexec is installed by default on all major Linux distributions (we exploited Ubuntu, Debian, Fedora, CentOS, and other distributions are probably also exploitable);
- pkexec is vulnerable since its creation, in May 2009 (commit c8c3d83, "Add a pkexec(1) command");
- any unprivileged local user can exploit this vulnerability to obtain full root privileges;
- although this vulnerability is technically a memory corruption, it is exploitable instantly, reliably, in an architecture-independent way;
- and it is exploitable even if the polkit daemon itself is not running.
Another app I use that has this problem is Spotify. While it isn't electron, it is using CEF (chromium embedded framework) and can be dynamically linked to a distro one with some effort. Using the web version means I dont have my music available offline for listening.
