United Airlines Ad Music

United Airlines has recently been running a TV commercial which features a bunch of sketches that fade from one to another. There is just a piano music bed [no ad dialog]. Is this a classical piece of music, or an original piece? Thanks to all!
If it's the Ad I'm thinking of, the music is Gershwin's "Rhapsody in Blue". Awesome in my opinion.
That's been United's theme song for decades.
Yes. And Thank You United for makin me sick of it! Maybe they could pick a snappy disco tune now that they have come out of Chapter 11.
