I was checking fares on UA's website and noticed several ads from OfficeDepopt. At first I thought "cool, now I'll get miles for buying stuff from them" then I noticed that it was just an ad. No bonus miles offer whatsoever.
Is it safe to assume that UA gets paid to put OfficeDepot ads on the website? Are they really that desperate for money?
For example, click here: (the ads rotate so it may be something else by the time you click it)
