Glad to see people like the EI product. Historically, 'premier' could be said to be positioned between F and J. In the 1990s it took a real dive, but with the new cabins things seem better. Looking forward to a J trip in two weeks time (DUB-ORD).
I wonder if some UA elites ("premiers") will be confused/argumentative because they think they are entitled to sit in "the Premier section," which is what some UA agents call E+, but which is actually the J cabin on EI.
