Hey, first of all, thanks so much for this amazing site! Just wanted to say that while the site appropriately checked me in the very first time I used it about a month or so ago, it hasn't worked for the past 3 flights since then, most recent one being today at 855 am MST from Denver to DCA. Looks like it's been working for others though, so not sure what it is about me specifically, or if it's something else. It confirms that it'll check me in when I initially put in my info but just never does.

Thanks again!

I tried to use this for 4 flights last night and it never checked me in. Just wanted to report it!
