Necessary to Give Flight Info?

[Woodfaerie]

I  have never bothered to enter my flight info when I do the final registraion for cruising as I always fly in the day before so I didn't think it was a big deal. The world is wonky so I figured I would supply that info for my upcoming cruise. Lo and Behold!  It doesn't recognize the airline!  Anyone ever have this issue?  (if you  are wondering, its Aveloair)

its not needed nor required

I’ve never entered flight info. I’d guess it is more for those flying in the day of cruise and using Carnival transfer to the pier.
