84,000 tier miles this year, all in C, so was expecting nothing.
And stragely enough, thats exactly what I got.
Not complaining though, been upgraded from C to F on every flight where there has been F, and my wife got upgraded Y to C this trip, on a reward ticket. She got lounge access too whilst in Y, as did my daughter and her boyfriend, also travelling on a Y reward trip.
Sorry, but EK still get my vote for getting it right !!
