League of Legends on an Airplane

So I saw two threads on this topic, neither really provided information. I am boarding a plane for Portland today, probably will be around an hour or two. (playing aram so I wont have to stop mid game. shorter game = better). My mother has a lot of frequent flyer perks since she's always traveling for business, so I get to use the wifi for free. You normally have to pay for it, so my assumption is a lot of people on the plane won't be using it, so it will most likely run better than if it was completely free for everyone to use. I'm not trolling, joking, nor stupid, but what are your thoughts on this? Will I lag into oblivion or do you guys think it would work and be a fun experiment? I'll be sure to post a testimonial after the plane ride for those interested. Hahaha. Yes, I will hopefully get har har har.
