Looks like a USB-A female plug. Quite commonplace in international flights.

As others have noted, this looks like a standard USB-A port, and cables are readily available for charging to connect USB-C to USB-A. USB-A ports are pretty much standard on all kinds of chargers - plug-in wall-warts, permanently installed receptacles, outlet strips.
There are two special concerns using someone else's charger:
It is possible (not saying "probable", but these things are out there in the wild) to hack in to a device via USB. A charger should only be sending power with no data, but you can't tell by looking at it. Not an issue to charge up your wireless headphones or other relatively simple devices, but potentially an issue for charging a smartphone. A malicious device could try to read information from your device or try to infect it with a virus or other malware.
The safest method, by far, is to plug in your own wall wart into a mains (110V - 250V, depending on the country) connection, so that you are assured of only getting power from someone else's system and not any risk of data. But that is not always an option, and USB-A charging outlets are ubiquitous.
Thanks to Criggie for the reference to USB Condom which is a device that solves this problem, though possibly at the cost of slower charging.
There is a small possibility (e.g., see comment "Zooming in, it almost looks like the metal has been damaged, as if someone broke it by putting something too large in it.") of a damaged connector. USB should be smart enough to detect a problem and simply not charge. But there is a possibility of a damaged connector resulting in damage to your device rather than triggering a self-shutdown (e.g., breaker trip). Again, not easy to check for this as most people don't carry around a USB tester:
Sample picked semi-randomly from Amazon. Many different types are available.
