Step 3: Go to the local airline's website
If you don’t know how to search for an airline’s website, just Google "How to find an airline's website." More likely, just Google that airline’s name.
Step 4: Once you're on the site, change your country of origin to the airline's base
Some airlines, like Norwegian, ask you before you enter the site which country you're searching from. Others require you to select from a drop-down menu at the top of the page. If you're in the United States, it'll default to USA, so you’ll need to change that. It’s not a Global Entry interview, so go ahead and lie.
After selecting that airline’s country of origin, you'll likely notice the site changed languages -- don’t panic, airport codes and dates are universal. If all else fails, though, call your buddy who speaks Norwegian. Kidding. Again, use the Internet to translate any unclear text.
