No doubt that FEA is a very popular ride and the lines tend to be really long, but some of it is luck of the draw and how many FP+ show up while you're in queue.
The only time we rode it was last summer. I forget exact dates now, but we rode it something like July 2nd or 3rd. The ride opened in late June, so it had only been open for a few weeks. That was when there were stories of 3-4 hour waits. Our first day at WDW was something like June 18th, but we stayed away from FEA because we knew what it would be like since it was the grand opening, and we couldn't get a FP+. One of those early days, we rode the monorail from MK to Epcot, and we could see the line stretching all the way out (I think it was the monorail, but anyway, I remember seeing the line). So our last day in Epcot, we got there right around park open...we don't do 45 minute early rope drops. We walked quickly to Soarin' and got right on. We then had a FP+ for TT, which we did. At that point, it was something like 9:45am. We had time to kill before our next FP+, and were trying to decide what to do. I knew DD9 really wanted to ride FEA...I could see that sad look in her eyes of "We're not going to get to ride it, are we?" So I pulled up the Lines app...it said that the posted wait time was 90 minutes, but the actual wait time was 45 minutes. We decided to just go for broke and try it. We hustled over to FEA and were amazed. Sure enough, a CM was standing outside with a sign saying the wait was 90 minutes. But we walked in and the line wasn't horribly long. We saw very few FP+ going through, so it was boat after boat of standby. We waited 27 minutes.
I know that was probably luck of the draw, and we chalked it up that way, but you never know. Keep an eye on the line times, I like the Lines app, and you may get lucky.
