If it's not allowed, that's fine, but the policy needs to be clear in the website. I would have packed differently had I known.

In my situation, I am not getting a hotel for the overnight It's pointless -- with 3 hr jetlag I would not get any sleep anyway. I just landed in JFK; I'm going to grab a lyft to manhattan and go out all night, and be back at the airport in plenty of time for my 7am flight. Having a bag in tow is not what I'm looking for.
