„When Jennifer Null tries to buy a plane ticket, she gets an error message on most websites. The site will say she has left the surname field blank and ask her to try again.

Instead, she has to call the airline company by phone to book a ticket – but that’s not the end of the process.

“I’ve been asked why I’m calling and when I try to explain the situation, I’ve been told, ‘there’s no way that’s true’,” she says.“

PS:
It‘s an old story... wondering as a non backend Developer whether this problem is today mostly covered or still exists?
