Yup, on UA I'm pretty much going to fly coach class because 1) it's pricey to upgrade, and 2) you can never upgrade anyways, since UA tends to always have incredibly long eligible upgrade lists.
On DL I have a chance of sitting in business. Of course, DL doesn't do nonstop SFO-LHR, so the stress of making it onto four flights instead of two flights for the roundtrip...probably erases the benefits of sitting in business.
