The last I knew, the only wifi at the airport was at the bar inside security and you have to get the password from them. But regardless, do yourself and the folks at the airport a favor and get a printed out copy. It is expecting a lot of airport security to have to squint to look at everyone's phone to read their results. It will make their day better--and quite possibly yours--if you have a printed out copy. Anything you can do to NOT annoy security people is a good thing for yourself, and your fellow travelers.
