This isn’t quite the same thing, but a friend wasn’t allowed on an airplane because their surname was double barrelled with a hyphen in the middle (I.e. Smith-Jones). The airline seemed to strip the hyphen, so their boarding pass said SmithJones, but their passport said Smith-Jones. They missed their flight and they weren’t able to get a refund or compensation like you would usually be able to, because the airline refused to acknowledge that they had fucked up. My friend ended up having to take it to small claims court, where they won by default.
