Thanks for the info. Now actually considering not using the Norwegian tickets. I noticed they have a free rebooking offer for tickets bought before some date in august which can be rebooked until October. Could this be combined with a name change and/or using the total credit amount for the three flights I have for rebooking fewer flights but more expensive ones? I might not be able to use the tickets before October but a relative might. Also, does it matter if you booked through a travel agency and not direct with Norwegian?
