Oh, good points. I didn't check bags, but I did use the SkyClub and bought wi-fi on the flight, so I can message DL with that info.
Also, this was an international flight (JFK-SXM), so I would have expected some other problem to come up because of this. I guess Saint Martin is just chill about this type of thing, lol?
