Our JB flight out of Ft Lauderdale on 4/7 went from a seating of 3 and 3 to a 2 and 2 without any notification either. I just happen to go onto the site to check something and noticed that the seating and plane was changed. My concern was we were in row 1 due to my husband vision issue, when I called that row was gone. We are now in row 2 which I will accept, but it awful that there is no notification to anyone when changes are made.
