Air Wisconsin is a small regional partner of American Airlines, at least in the situation I flew them in. I was delayed on a flight from London, spent the night in a hotel in Chicago, and then flew Air Wisconsin home to Omaha on the last leg.
It was a pretty standard smaller airplane, similar to others used on short-leg AA flights. The smaller size of the plane meant that the carry on bag I had used for my whole trip now did not fit and had to be gate checked. After all the delays, I did not care about that - I just wanted to be home.
The staff on board were very nice, though, which was appreciated. Our main flight attendant's name was Eliza/Elizabeth (couldn't fully read the name tag), and she was super friendly on an early flight with a bunch of grumpy people coming from a delay.
If you are having a short midwestern flight and end up on Air Wisconsin for your regional leg, they're a pretty standard provider, but with some great staff who will make the flight a little easier/more comfortable. read more
