The website is an ongoing rolling dumpster fire, so I wouldn't attribute to malice what can adequately be explained by stupidity. I can't get either Chrome or Firefox to display the sale roster correctly, and the scripts just cause delays site-wide. I'm sure they'd blame me or anyone else for not having the latest OS or browser version, but when you fall back on that you should know you're losing a lot of business.

I had to register twice and may have lost an ATL-IAD one-way credit, but just getting the e-mail verification e-mail was an unexpected hurdle.

There's probably a lot of competition for talent in the IT sector as pertaining to all this, as you've got not only the other airlines but tons of third-party CRSes. Frontier is probably low on the totem pole.
