After the rush of Chicago, it is a delight to know that there is a decent British Airways lounge at the airport. Indeed, there are two, for there is also a separate small First Class lounge, and it is one of the few locations outside London where you'll also find a separate First dining room. The First Class lounge at Chicago is a little bit like a corridor stuck on the side of the airport terminal. This isn't a bad thing, as it has the joy that the Terraces on the other side doesn't have: windows. Great big floor to ceiling windows.
