Question about NCL free airfare

[flowergirl22]

I have booked a NCL cruise out of NOLA (2/7/20).  The promotion I booked under includes free R/T airfare.  After speaking with NCL, I was informed the return fight must be the day of disembarkment (2/16/20).  Well I want the stay in NOLA another 4 or 5 days to enjoy the Mardi Gras activities.  So, my question is, can I call the day of the return flight and cancel, or just fail to show up for the return flight.

Go  to the Cruise Air  board,  and post.   Plus read  the stickies.    Solid accurate information.
