I got my boarding passes but noticed that I had forgotten to make seats reservations, on the website it says that if I don't choose my seats then I will be assigned seats on the day of the departure. Does this means that I have to get there a bit earlier and go check-in in person? Or just carry my boarding pass and head straight to the gate?
When we book Norwegian, we don't book seats as it's cheaper. I scan my barcode at the airport check-in kiosk and it prints for me my boarding pass with a seat mentioned on it.
You can also check-in online within 24 hours before the flight.
