It was as expected for such a short flight. No complaints

Great thanks - a whole row to myself. Good food but film selection not great.

Just about made it for the next flight. They need to put in longer layovers if they know they close the gate 10 min before they take off. I will never do a layover for less than 90 minutes

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Best flight by a pilot I’ve ever been on as a 62 year old

After multiple delays (I lost count), the flight was canceled due to a "maintenance issue". So instead of a direct flight arriving at 5:00, I had to take a flight connecting through Chicago. That flight was also delayed, partially because the plane from the cancelled flight hadnt been removed from the gate and there was nowhere for the other plane to park. (Did nobody think this might be an issue during the hours after that flight was canceled?) The connecting flight out of Chicago was delayed as well. I didn't arrive until 12:30am the next morning. I should have just cancelled the trip. It wasn't worth the hassle and stress.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

Terrible. I didn’t fly and I had an important meeting the next day.
