This flight was actually 3 years ago. But I did fly out to San Jose yesterday and both of my flights were full. Mostly because they were morning flights. I know there are 3 flights out of BUR to PHX at the moment, I'd go for either the 2nd or 3rd one.
Possibly because people think it's "clickbait" because it's not a rEaL aborted takeoff where you get within a knot of V1 and then full reverse thrust, brakes, and spoilers. The majority of takeoffs that end up being aborted end very quickly, but the general public/avgeeks don't seem to understand that.
