Recently, I took a weekend trip from Indianapolis to Chicago, taking advantage of some e-specials on United. After a pretty significant ground delay due to bad weather, the FAs closed the door of our very clean A319 and said "It's going to be a very bumpy ride up to Chicago." Well, it was. I was seated in seat 11F, just behind the wing, and watched the engine bounce the whole way to Chicago, which is about 180 miles, 35-40 minutes flying time. The weather broke over Lake Michigan and we had a smooth descent into O'Hare.
On the way back, I flew stand-by on one of the summer season 767-300ER flights UA runs to Indianapolis from O'Hare. Seated in 33G, I marveled at the fact that they flew these heavies to a destination such as Indianapolis. The flight was packed, and most people remarked on how big the plane was for such a short flight. I enjoyed the personal TVs in economy (I had been in an identical plane from ORD-GRU a year earlier), the map, and the quiet of the plane. Personally, I find 767-300s to have cramped seating (KLM and LOT, for example), but UA was okay...and I'm nearly 6'2. Overall, pleasant flying experience. Just kind of can't figure out the point of using the 767-300ER on that route.
