If Canada/Caribbean(/Mexico?/Northern S. America?) is now called United First, what markets is United Business? I thought that was always only for the closeby international destinations on a narrow body, like Canada. It always confused me why they even did this since the product is identical to domestic F.

for those who want a history, pre-merger United always called front cabin to Canada First. Sometime shortly after the merger, they changed it to Business. I believe lounge access was always allowed.
