Not totally up-to-date on airline things, but:

I was referring to the competing GDS platforms that airlines like Southwest opted not to use. I was trying to be charitable to the author here, because I am partial to how the terminal booking interface just works and allows for almost universal interoperability. You just have to learn how to use it. Of course, there is still greater functionality when using the airline's website directly (dynamic pricing, seat choice), which is "patchy".

Opted not to use /until recently/
