I'm not sure if a US licence would be acceptable. You'd better check with the airline.
I (personally) wouldn't dare fly without my passport/ID for foreign nationals. You never know when they'll check that stuff.

Oh, I will!
Last time I was in the UK they scoffed at my British passport (it's legit!) and wanted my Canadian one (which, fortunately, I had.) it's always so random! I think they would laugh at me if I tried to get on a Canadian driver's license. But I am notorious for having bad border crossing experiences.
Oops, forked up quotes on my phone but I have to run!
