Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.

Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight
