I wonder if the do it yourself kiosk know or not. I'm trying to remember but I feel like someone used that and reported back on the thread that it didn't reflect a charge for them and they had purchased tickets prior to the May date.
If anyone tests the kiosks and should qualify for free baggage that would be great to report back how the machine saw their ticket. I know there are a variety of ways someone would get free luggage so we'd probably want to put if our status, credit card, or ticket purchased allowed for included luggage. I would test this ourselves but our trip next week won't be with checked luggage
