In North America, I just read some more fine print on UA.com that I never noticed before, that all flights in the US (not 3 class aircraft) have First and Y, and other places in North America (and Asia) are Business. I am flying from DEN-YYZ this week, and at first thought the difference was because it was Express.
I have flown Business on 3-class 777 domestically, and I'm sure there was some difference to the food in addition to the obvious difference in Hard Product, but what are the diffferences between First and Business when the Hard Product is the same? e.g. 738 flying from DEN-IAD vs DEN-YVR.
I try to understand from the descriptions online, but their website is vague, and just says things like "Gourmet" dining, etc.
