It was pretty great actually, I got far better service from airlines via Twitter (RIP) than I did by phone. It was a pretty well-known approach.
They do provide some support through Facebook via Messenger, but it was never as popular. TikTok isn't a great medium for this kind of thing but if it helps them reach their customers, why not?

Not in my experience, they just moved to DMs.
