For me it’s exactly the sort of thing that would be turned up in a first round of sense-checking an application. In the American Airlines example at least it’s a result of a technical error. In my experience these situations are as regularly present in working applications as they are in broken ones.

Garret, nice comment. I checked out that site and interstingly, their home page welcomes you with a list of supported browsers on the right-hand-side. It’s like an exclusive country club for browsers a kind-of virtual xenophobia and very 1996-like. thanks for pointing it out

Preventable errors topped with horrible error message writing. Pretty pitiful. My favorite is the one about having multiple browser windows open. Does that mean I can’t have my gmail in another window? Likely they are talking about instances of their own site, but they fail to communicate this with their users.

Other websites let you have multiple instances. Not efficient workflow, but possible.

You’ll find this interesting.

The other day I was withdrawing money from an ATM when I noticed a leaflet stuck on the door which basically explained all the error codes that one could receive while interacting with the ATM.

Better than nothing at all though it could have been located on the wall behind the ATM to increase effectiveness, but was rather amusing none the less.

I’ve had this exact thing happen to me once on the Eurostar website. I was told to start over, so I did. I ended up buying two tickets. After talking with them on the phone, they assured me I would only be charged for one ticket (I wasn’t) and there would be no problem traveling. Well, they canceled both tickets and charged me for both!

This entire scenario was caused by my “incorrect use” of the back button. I’m finding out that it’s a good policy to never use the back button when trying to buy something online.

There is no such thing as “Incorrect use of browser’s Back button”, just badly designed web apps.
It may as well have said “User error. You probably messed up in some way.”

Hi, Jared. Great article! I’m amazed how often I come across these types of issues. Here’s one from shopouraisles.com. They were gleeful to inform me, I was using an “incorrect web browser” (Safari).
